If marshal.dumps() is handling a large data, It keeps acquiring the GIL and may take several seconds, Other threads therefor are blocked. marshal.loads should also be friendly to other threads.

The patch is wrong; the function allows other threads to run while it calls _PyString_Resize(), this will lead to crashes.

In fact, almost no place in marhsal is thread safe, so releasing the GIL anywhere is not safe.
