Problems with APC and/or rsync

Hi all

Here's a list of the last 26 smoke reports sent from this FreeBSD
7.2-RELEASE box, sorted by subject:

As you can see, I've been smoking the same builds over and over
again. This *isn't* intentional. After poking around, I've discovered
that between APC and rsync, I'm being sent the same builds. Here's
what happened from 5 consecutive rsyncs:

bri@bsd:~/smoke/tmp$ /usr/local/bin/rsync -az --delete public.activestate.com::perl-5.10.x . ; cat .patch
maint-5.10 2009-05-27.00:14:05 a524575ae930f79c9d69eb19db19ad24b558b4f0 GitLive-maint-5.10-1218-ga524575

I've updated my rsync to the latest in the Ports collection (from
2.9.6?) and the same happened:

bri@bsd:~/smoke/tmp$ /usr/local/bin/rsync --version

I've also tried this on a Debian/testing box and the same happens. Can
anyone give me a clue as to what's happening and how to put it right?
