Gaah. Locking problem. We really should have let this one simmer in
-devel a bit longer before rushing it into -stable.

Attached potential patch. Untested, but I forgot about the locking in
the first version of the patch, and then the "trivial one-liner fix"
missed the deeper problem.

Greg - please don't use this patch yet. I'll test it. And wait for
verification that it fixes other peoblems too.
