No real problem here, it's just that most of a year of my life
has been watsed with __db* files. That has nothing whatsoever
to do with you.

Try
	cd /var/lib/rpm
	/usr/lib/rpm/rpmdb_stat -CA
and watch the output. Run rpm -qa as root, ^Z out, and you
will se a lock appear. Restart the rpm -qa, run to completion,
watch the lock disappear.

Repeat, but kill the rpm -qa with kill -9, watch a persistent
stale lock be left behind.

Then try running rpm -qa while installing, as that's the "feature"
that these locks are about, concurrent access.

In fact, try installing 2 packages simultaneously, that works.

Can you break concurrent access by installing hundreds of pkgs simultaneously?
Sure, feel free to do so, if the problem is exactly reproducible, I
may even have a prayer of attempting a fix.

Anyways, I dinna mean to be gruff, apologies.
