hg push getting worse?

[Mark Reinhold]

I've written a script to reap old changegroup snapshots, and removed
all snapshots older than 14 days (excepting the latest snapshot of
each repo filesystem).  A push to hg.ojn now takes about 20 seconds.

I'll set up a cron job to reap snapshots on a regular basis.

Further improvement will be possible after we migrate to the new
datacenter, but for now 20 seconds << 5 minutes.
