Call timeBeginPeriod (1) somewhere upon elaboration of Claw, and then you
will be able to wait for 1ms. Note that it is not just Sleep, which depends
on this setting, actually all waitable timers and scheduling are. The
effect of timeBeginPeriod is global (I like Windows (:-)), which is not
bad, unless you have some 66MHz i486.
P.S. I think it is 1ms since Windows XP.
