 * relationship of job descriptors to shared descriptors (SteveC Dec 10 2008):
 *
 * ---------------                     ---------------
 * | JobDesc #1  |-------------------->|  ShareDesc  |
 * | *(packet 1) |                     |   (PDB)     |
 * ---------------      |------------->|  (hashKey)  |
 *       .              |              | (cipherKey) |
 *       .              |    |-------->| (operation) |
 * ---------------      |    |         ---------------
 * | JobDesc #2  |------|    |
 * | *(packet 2) |           |
 * ---------------           |
 *       .                   |
 *       .                   |
 * ---------------           |
 * | JobDesc #3  |------------
 * | *(packet 3) |
 * ---------------
 *
 * The SharedDesc never changes for a connection unless rekeyed, but
 * each packet will likely be in a different place. So all we need
 * to know to process the packet is where the input is, where the
 * output goes, and what context we want to process with. Context is
 * in the SharedDesc, packet references in the JobDesc.
 *
 * So, a job desc looks like:
 *
 * ---------------------
 * | Header            |
 * | ShareDesc Pointer |
 * | SEQ_OUT_PTR       |
 * | (output buffer)   |
 * | (output length)   |
 * | SEQ_IN_PTR        |
 * | (input buffer)    |
 * | (input length)    |
 * ---------------------
