I'm afraid I don't have any advice here that I can give off the top of
my head.  I have no clue what work would involve threading and
parallelizing the unzip to begin with, much less advice to fix what I
fixed while achieving your goal...

I would probably have to spend some considerable amount of time
researching before I could even come up with something tangible. :-(
