That takes 26 seconds on my system and runs 5000 tests. What I really wanted 
was this:

 llvm/tools/clang/test$ /home/stephen/dev/src/llvm/utils/lit/lit.py --param 
build_mode=. -sv  . --filter linux-header-search

I had to debug a lot of "error: expected string not found in input", so 
waiting 30 seconds between runs does not make sense.

Updated patch attached.

Thanks,

Steve.
