There is definitely something to this.  If I take a random failing
testcase and run the test in isolation in the shell, it works.  So what,
if anything, does lit/FileCheck/etc. do that might run interference
if there is another copy of lit/FileCheck/etc. running at the same time?
I tried strace -etrace=file but nothing obvious pops out.
