Good point. I think that is because gc does not check if gc is already
running. Adding such a check should not be too hard. I think gc could
save its pid in $GIT_DIR/auto-gc.pid. The next auto-gc checks this, if
the pid is valid, skip auto-gc.

Some improvements could be made in gc, for example warn users about
upcoming gc so they can run it in background (of course the above bug
should be fixed)

or speed up repack by implementing pack-objects --merge-pack:

Or you could just make a cron job to gc all repos every week and the
problem goes away ;-)
