[LLVMdev] lit test suite on Windows always hangs.

[Zachary Turner]

I'm using Windows 8.1, and every time I run check-clang, I eventually end
up with a bunch of hung processes.  Generally this is an instance of
clang.exe, a bunch of instances of FileCheck.exe, and occasionally an
llc.exe and an opt.exe.

Inside, the processes are all hung inside of calls to WriteFile()
attempting to write to stdout.

I notice some of the tests fail with output indicating that it expects a
unix-like environment.  For example:

207>  ********************
207>  FAIL: Clang :: CodeGen/2004-06-17-UnorderedCompares.c (1109 of 7263)

207>
207>
207>  --
207>
207>  ********************

Any suggestions?
