to work, so we now default to using sync io.

Also added --async-io flag.

cda92de441 [thin_check (rust)] Add a threaded version of btree walk. 
Bottom level mappings use this if there are few devices.  Performance
is a bit slower for io_uring, and much slower for sync io (which I think
is due to io scheduling which I can't do much about).
