numbers and handle types in rational way. This will better protect from (unwittingly) dealing with stale handles/commands. Fix the watchdog timeout code to better protect itself from mistakes. If we run an abort on a putatively timed out command, the command may in fact get completed, so check to make sure the command we're timing it out is still around. If the abort succeeds, btw, the command should get returned via a different path.
