It looks like (1) someone else has has this problem and (2) it's a FreeBSD
kernel bug.

There's a thread in the freebsd-hackers mailing list, entitled "How best to
debug locking/scheduler problems", where just today John Baldwin posted a patch
that allegedly fixes the problem. The message-ID is
<h1bmmg$s7t$1 at FreeBSD.cs.nctu.edu.tw>.

I haven't yet tried applying the patch and seeing whether the problem goes
away. Since it's very intermittent -- it's happened to me twice, with an
interval of a few weeks -- it may be difficult to tell, but I'll apply the
patch and report back here if the problem recurs.
