Divert sockets are known to have lock order reversals which can cause
deadlocks under certain situations.  I think this particular one has
not been reported, so you might like to send it to bz at FreeBSD.org for
inclusion in his list (http://sources.zabbadoz.net/freebsd/lor.html).

You might like to ping the net@ list to see if anyone is working on
fixing these problems.
