Fwiw the python build-in handling of some archives is an order of
magnitude slower, than on a uncompressed file. From brief testing,
extracting is almost always a (time) win.
Ages ago I was debugging a pathological case where a sub 20MB
(compressed) binary package was of taking well over 6 _minutes_ IIRC
with namcap. Will polish and send up my patches over the next few
days. They help significantly, in said said case and overall.
