RE: [ECOS] win2k download utility

That would still waste some CPU cycles that could have been used
somewhere else.  I've never used Sleep in windows myself.  I usually
just set a timer, and let windows deal with when I should receive the
message.  It's not always perfectly accurate, but for a non-realtime
app, it doesn't really matter that much.  It's usually completely
accurate when the system is not loaded.

Well, it was a DOS program, designed for single-tasked operation :)))

BTW, as a random aside: Sleep() in Win32 doesn't seem to give quite the 
expected results to me. It's better to have a polled loop that peeks a 
message queue and terminates when time() exceeds some known value.
