--- Comment #14 from Guido Falsi <madpilot@FreeBSD.org> ---
(In reply to luscent@gmail.com from comment #13)

The problem strongly looks like a race condition. Two (or more) async events
need to happen in a specific order for things to work correctly. If they ha=
ppen
in a different order things lock up.

But being asynchronous events they can happen in any order, so it's a chance
thing.

It's also possible that running in a VM makes the wrong order more probable=
 for
some reason than on real hardware. It is also very common in this kind of
situation for the broken behaviour to not show up when running in a debugge=
r or
tracing tool (like truss(1)), due to the timing changes such tools impose.

This is a difficult kind of bug to diagnose.
