I've seen this backtrace before. It is unusual in the way that it looks
like it crashed in the 'IsDir' test. It looks like the object got pulled
out from under us even though we still had a reference count on it.

I guess your local cache held fewer files than were being used in the
bonnie dataset so there was replacement going on and some destructor
must be a bit too destructive.

The other crash you reported on the wiki (disconnected startup crash) is
something I hadn't seen before. It is somewhat clear what is going on.
Right after startup the fake /coda/ directory must be still empty and
instead of returning ENOENT the directory handling code decided that
this is unusual enough to trigger an assertion, I'll try to replace it
with returning ENOENT back up to the caller. The only thing that puzzles
me is why this doesn't happen every time we (re)start venus.
