+/* A worker thread that monitors host connections, and registers a transport for
+ * every new host connection. This thread replaces server_socket_thread on
+ * condition that adbd daemon runs inside the emulator, and emulator uses QEMUD
+ * pipe to communicate with adbd daemon inside the guest. This is done in order
+ * to provide more robust communication channel between ADB host and guest. The
+ * main issue with server_socket_thread approach is that it runs on top of TCP,
+ * and thus is sensitive to network disruptions. For instance, the
+ * ConnectionManager may decide to reset all network connections, in which case
+ * the connection between ADB host and guest will be lost. To make ADB traffic
+ * independent from the network, we use here 'adb' QEMUD service to transfer data
+ * between the host, and the guest. See external/qemu/android/adb-*.* that
+ * implements the emulator's side of the protocol. Another advantage of using
+ * QEMUD approach is that ADB will be up much sooner, since it doesn't depend
+ * anymore on network being set up.
+ * The guest side of the protocol contains the following phases:
+ * - Connect with adb QEMUD service. In this phase a handle to 'adb' QEMUD service
+ * is opened, and it becomes clear whether or not emulator supports that
+ * protocol.
+ * - Wait for the ADB host to create connection with the guest. This is done by
+ * sending an 'accept' request to the adb QEMUD service, and waiting on
+ * response.
+ * - When new ADB host connection is accepted, the connection with adb QEMUD
+ * service is registered as the transport, and a 'start' request is sent to the
+ * adb QEMUD service, indicating that the guest is ready to receive messages.
+ * Note that the guest will ignore messages sent down from the emulator before
+ * the transport registration is completed. That's why we need to send the
+ * 'start' request after the transport is registered.

-/* A worker thread that monitors host connections, and registers a transport for
- * every new host connection. This thread replaces server_socket_thread on
- * condition that adbd daemon runs inside the emulator, and emulator uses QEMUD
- * pipe to communicate with adbd daemon inside the guest. This is done in order
- * to provide more robust communication channel between ADB host and guest. The
- * main issue with server_socket_thread approach is that it runs on top of TCP,
- * and thus is sensitive to network disruptions. For instance, the
- * ConnectionManager may decide to reset all network connections, in which case
- * the connection between ADB host and guest will be lost. To make ADB traffic
- * independent from the network, we use here 'adb' QEMUD service to transfer data
- * between the host, and the guest. See external/qemu/android/adb-*.* that
- * implements the emulator's side of the protocol. Another advantage of using
- * QEMUD approach is that ADB will be up much sooner, since it doesn't depend
- * anymore on network being set up.
- * The guest side of the protocol contains the following phases:
- * - Connect with adb QEMUD service. In this phase a handle to 'adb' QEMUD service
- * is opened, and it becomes clear whether or not emulator supports that
- * protocol.
- * - Wait for the ADB host to create connection with the guest. This is done by
- * sending an 'accept' request to the adb QEMUD service, and waiting on
- * response.
- * - When new ADB host connection is accepted, the connection with adb QEMUD
- * service is registered as the transport, and a 'start' request is sent to the
- * adb QEMUD service, indicating that the guest is ready to receive messages.
- * Note that the guest will ignore messages sent down from the emulator before
- * the transport registration is completed. That's why we need to send the
- * 'start' request after the transport is registered.
