[CentOS] Diagnosing random hangs

I would recommend Xming (http://sourceforge.net/projects/xming) instead 
of Cygwin/X. It runs noticeably faster than Cygwin/X, and is even faster 
if you use fullscreen mode. We have also had trouble with a Windows 
webcam driver breaking Cygwin/X, but it did not interfere with Xming.
