:Hi Matt,

No luck. I couldn't get it to crash.
Hmm. Rumko, this is a bit drastic but here's a patch that
will add serious debugging output to the console. I kept
the old patch too. Please run this and upload a core from
it when it crashes. I may be able to figure out where the
vnodes are being allocated from by looking at the backtrace.
