Antoine, maybe you could clarify the situation regarding buffer-locks for me. In older versions of PEP 3118 the PyBUF_LOCK flag was still present but it doesn't seem to have made it's way into the final draft. Is it save to assume that a buffer-view will not change until release() is called - for all types supporting the buffer protocol in py3k ?? I've done some testing and the overhead of releasing and re-locking the GIL is definitely a performance problem when trying to hash many small strings (doubled runtime for 100.000 times b'abc'). I've taken on haypo's patch to release the GIL only when the buffer is larger than 10kb.
