I've installed the newest snapshot and recompiled the test case, but it still hangs on my system. I'm sorry for interfering with your release. Is there any further information I could provide to solve this issue? Just to be sure: $ uname -a CYGWIN_NT-6.1-WOW64 zoppo 1.7.18s(0.263/5/3) 20130329 13:18:55 i686 Cygwin My installation of Windows runs in a virtual machine. Could this maybe influence the race conditions? I've noticed that the resolutions I get with clock_gettime(CLOCK_REALTIME, ...); are quite coarse (a few milliseconds!) in comparison to my Linux system (nanoseconds), or is this a general Cygwin thing?
