Okay, we'll have to continue this thread. I have no ideas yet. :-)

For some reason, we've noticed that a DB environment has the potential
to get 'wedged' every once in a while, and needs to be 'unwedged' by
the db_recover utility.

It seems to happen if a DB-using application ever suddenly dies, or if
you interrupt it with a signal. It's not perfectly reproducible, so
we've not done a lot of investigation into the problem. But
*sometimes* we can reproduce it by simply running 'svnadmin lsrevs
repo', and then hitting control-c. Really weird.
