As we discussed today, I've completed the disk polling at the point where we suspend for disk full. This pauses and restarts automatically as space is insufficient and made available. I also added a guard against obtaining a map read/write accessor if the store enters a fault state (basically if an mmap API fails during remap), and the fault results in a flush.lock turd on shutdown (as with any process termination), which forces an automated restore from snapshot upon nest startup.
