Optimisations with loops when running update.experimental
Use printf's formatting instead of for loops, and tee instead of cp.
Use --fast with gzip.
The biggest slowdowns are the bunzip2s on MANIFEST files, but not much
can be done about those.
The changes together shave roughly 3 seconds off here, but it's all
going to be relative to the local system.
