Is changing from an RLock to a Lock intentional? Are you sure it isn't going to
cause you to deadlock?

It's intentional, the code doesn't have any recursive lock anymore.

+      # On cygwin, it's throwing randomly. Hack and reuse the single
+      # sys.stdout.lock. Yep you read it right. Single lock.
