Hello.

I get this panic today:

recurse on non-recursive lock (sleep mutex) rentry @ /usr/src/sys/net/route=
.c:1297
first acquired @ /usr/src/sys/net/route.c:182

db> trace
rt_check+0x19c
ether_output+0x62
ip_output+0xc66
tcp_output+0xab3
tcp_timer_persist+0x129
softclock+0x1ad
ithread_loop+0x177
fork_exit
fork_trampoline

How to repeat:
I can reproduce this panic by removing all routes and adding for example:

	# route add -net 10.1.0.0/16 10.1.253.253

I got little patch for this, but I'm not sure if my fix is correct
(it works for me, but maybe it's just a workaround):

	http://garage.freebsd.pl/patches/route.c.patch

As you can see I added one more additional check for simlar situation,
but maybe it's just useless.
