I've submitted the zlib patch as patch #1435422. I added some test cases to test_zlib.py and documented the new methods. I'd like to test my gzip / tarfile changes more before creating a patch for it, but I'm interested in any feedback about the idea of adding snapshot() / restore() methods to the GzipFile and TarFile classes.

It doesn't look like the underlying bz2 library supports copying compression / decompression streams, so for now it's impossible to make corresponding changes to the bz2 module.

I also noticed that the tarfile reimplements the gzip file format when dealing with streams. Would it make sense to refactor some the gzip.py code to expose the methods that read/write the gzip file header, and have the tarfile module use those methods?
