Nadeem Vawda added the comment: Yes, that's because the builtin map function doesn't handle each input in a separate process, so it uses the same LZMACompressor object everywhere. Whereas multiprocessing.Pool.map creates a new copy of the compressor object for each input, which is where the problem comes in.
