Subject: Problems with Windows threads and cygwin sleep()

There seems to be some kind issues with cygwin sleep()
and Windows threads.
I created one test program which creates 600 threads
with native windows Sleep(1).
Now when I compile simple c program under cygwin

while(1) { sleep(1); }

and execute it, the first program will eat 100% CPU.

It does not have any problem with Mingw compiled version.
Then I tried compile it under cygwin, using native windows
Sleep() ( Uppercase ) and included w32api/windows.h header,
then it does not have this issue.

I discovered this, using rsync. When I changed rsync sleeps,
with native versions, then there seems to be still same issue.
Maybe cygwin uses inside dll sleep?

I really hope to get this issue fixed
