Thanks. This seems to fix the unmountable fs problem, so I'd guess it's
reproducing something related.

The test still fails occasionally with a trans abort and I see some
bnobt/cntbt corruption messages like the one appended below, but I'll
leave to you to decide whether this is a regression or preexisting
problem.

I probably won't get through it today, but I'll try to take a closer
look at the patches soon..
