I've never had this problem. It seems unlikely...

I was unable to reproduce this on any Mac or Linux, but it was really happening on the WinXP system.

Are you sleeping on a scalar variable or a constant value? Are you
operating in a single thread? Are you dependent upon any XS code?

constant value
not sure about the thread issue - good point.
XS code - I don't think so...


I guess you could try stuff:
Another way to sleep is to use select() routine with a timeout .

that was one of my first suggestions select(undef, undef, undef, $sleep_time);

Thanks.  ;-)

Another thing you could try: I tend to use the HiRes timer package.

Worse case, you could multiply your "delay time" by some value and
loop that amount of time on some busy wait. Interesting as a
diagnostic, anyway. Or you could system() out to some C routine that
you know does a proper delay.
