Confirmed on a nt4ws.sp6 system, compiling the while(1) program with MS
Visual C++ 6.0. The system was still running its services like ftp, etc,
but the UI was totally useless. Even Ctrl-Alt-Del did not work. Mouse
would move, but couldn't click anything.

What's interesting is...the test program was also compiled with Cygwin's
Cygnus Win32 gcc compiler....and the problem did not occur. It seems this
might be a bug with MS C stdio libraries?
