+ * relationship of subsequent job descriptors to shared descriptors:
+ *
+ * ---------------                     ---------------
+ * | JobDesc #2  |-------------------->|  ShareDesc  |
+ * | *(packet 2) |      |------------->|  (hashKey)  |

+ * | *(packet 4) |
+ * ---------------
+ *
+ * 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)    |
+ * ---------------------
