- Not improved: the horribly lousy name. :)

 - Suppress stderr when capturing output.

 - Rewrite which() to do the right PATH search instead of being lazy and
   shelling out to 'which'.

 - On Windows, run scripts as batch files (via 'cmd /c ...').

Usage: from clang/test, 'make -f ../utils/test/Makefile.multi'

Pros: About 20% faster than the Makefile based version on my 8 core
box (way faster on Windows I imagine, if it works).

Cons: Needs some cleanup. Ctrl-C works quite poorly on Darwin; more
Python's fault than mine.

Future: Support config definitions so we can use this for running LLVM
tests instead of dejagnu. Parallel testing goodness? Indeed.
