+ * 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)    |
+ * ---------------------
