Content
Note that on Windows if you redirect the standard streams then all inheritable handles are inherited by the child process. Presumably the handle for f_w file object (and/or a duplicate of it) created in one thread is accidentally "leaked" to the other child process. This means that shutil.rmtree() cannot succeed until both child processes have exited. PEP 446 might fix this, although there will still be a race condition.
