you need to be careful -- if you replace those delays with tsleeps,
you also need to add lockmgr() locks in the right places to keep
other processes from getting in there to screw things up.

delay() sort of enforces multi-threaded programming, and we need to
purge it for that reason anyway, but just so you're aware... :-)
