it speeds up gettimeofday() calls significantly,
and makes certain that the call is answered atomically,
Apparently important for databases,
which make many such calls
( drop from ~300 cycles for the call to ~200 cycles, more or less ).
still digging for the rest, and just discovered the previous reply,
which I'm gonna dig into in a moment...
Thanks, btw, eh?
Ach, me noodles are done...
