I did it cheaply using popen, but the seek times were terrible and it just
wasn't worth the saved space.  If it were to be done properly you would need
to be able to get gzip to save state at the beginning of each file in the
archive so you could use that information to seek (which I expect you should
be able to do, but I'm too lazy to look).  Either that or you would have to
be careful how you ordered the files in the archive, or temporarily
decompress everything into a directory.
