Same here, just a busy-arrow, no other hang.

I notice that if you call the Win32 version of Sleep() (capital S)
instead of Cygwin's sleep() there's no busy-arrow.  Also, a MinGW
version of the program doesn't show the busy-arrow either.

So there is something in particular about the Cygwin implementation of
sleep(), which is really just a wrapper around nanosleep(), which itself
really just calls cancelable_wait(), which in turn relies on
WaitForMultipleObjects() with a delay.
