[PATCH] D39039: Lit: Implement RWLock to serialize retrying flaky test.

[NAKAMURA Takumi via Phabricator via llvm-commits]

chapuni created this revision.
Herald added a reviewer: modocache.

To stabilize flaky tests, I thought they may be serialized after 2nd attempt.

I added rwlock object in litConfig and I know it is in wrong place. Any better idea?
