Hi, Very good idea. However, you don't need to discriminate for the bytes type specifically. When a buffer is taken on the object (with PyObject_GetBuffer()), the object is internally "locked" until the buffer is release with PyBuffer_Release(). Try with a bytearray and you'll see: if you resize the bytearray while hashing it in another thread, you'll get a BufferError exception. All in all, it should make your code and macros much simpler.
