ensure packets are processed in order

File operations that happen after the open packet has been received,
like reading/writing, can be done with the pool as the order they are
run in doesn't matter (the packets contain the file offsets).

Command operations, on the other hand, need to be serialized.

This flips between a pool of workers for file operations and a single
worker for everything else. It flips on Open and Close packets.
