I'm making good progress on the journaling layer. It will

in case the stream connection breaks and needs to be re-created (as would
happen quite often for an off-site journaling stream), without losing
any data, and to handle data backups that occur if the STREAM is a slow off-site link or if a glitch occurs. The MEMORY FIFO will allow us to
batch operations, reducing context switches and allowing me to implement
the worker thread concept as a very efficient asynchronous design.
