FWIW, any testing at all would have caught this.  It paniced on unmount
in a kernel with INVARIANTS.  The awkward thing about testing it is that
it requires a server.  We'd have caught it sooner if we hadn't had a
major stall in merging FreeBSD head to CheriBSD.

We're hoping to stop using it because it's slow, server support will
eventually go away, etc.  We don't really have an opinion about it
staying or going.
