Wow. The lock is precisely there so that the buffered object doesn't have to be MT-safe or reentrant. It doesn't seem reasonable to attempt to restore the file to a "stable" state in the middle of an inner routine.

Also, the outer TextIOWrapper (we're talking about sys.stdout here) is not designed to MT-safe at all and is probably in an inconsistent state itself.

I would rather detect that the lock is already taken by the current thread and raise a RuntimeError. I don't think it's a good idea to do buffered I/O in a signal handler. Unbuffered I/O probably works.

(in a more sophisticated version, we could store pending writes so that they get committed at the end of the currently executing write)
