Robert, Seth,

We've had so many issues with the futex issue that our auto-update
script has a ton of logic in it before calling yum update.

We run "/usr/lib/rpm/rpmdb_stat -c -h /var/lib/rpm | grep 'current
locks' | cut -f 1" and if the number is not 0, we remove
the /var/lib/rpm/__db* files and rebuild the RPM database.

It's surprising the number of rpm --rebuilddb's we run on a daily basis
across 7,000+ RHEL 3 and 4 hosts.  A bunch of fixes were put into place
on RHEL 3 Update 5's rpm, so we've pushed it to all RHEL 3 boxes
(including those not yet running Update 5+).  It reduced the issue, but
we still have a few hundred rebuilds a day and we've haven't been able
to track it down.
