Psyco

Using the Psyco JIT compiler could provide speed increases for backups that are CPU bound. I added this to the /usr/bin/rdiff-backup file: 

try:
    import psyco
    psyco.full()
except ImportError:
    pass

Hi a year ago or so I tried sticking in Psyco. Although rdiff-backup is often CPU bound especially when run locally, Psyco didn't seem to help at all. I noticed almost no speed increase when using it. Perhaps things are different now though.
