Thanks for the testcase.  The reason for the problem is this:
I optimized a condition in Cygwin's POSIX timers "gettime" method.
I optimized it so effecively that it was practically invisible :}

I pushed a patch and uploaded new developer snapshots to
https://cygwin.com/snapshots/

Please test.


Thanks,
