And found another livelock with CYGWIN_NT-5.2 F8G6S6D42HGDY4
1.7.18s(0.263/5/3) 20130309 21:57:01 i686 Cygwin provided in
http://cygwin.org/snapshots/cygwin1-20130309.dll.bz2
I can't submit proper bug report. it just hangs during CTRL+C for
arbitrary cygwin executable and there is nothing i can do except dumping
backtrace. If you don't care about it, it's ok to ignore this. please
pass by.
