Description of problem:

I've noticed the following warning in /var/log/messages:
=============================================
[ INFO: possible recursive locking detected ]
2.6.17-1.2630.fc6 #1
---------------------------------------------
setxkbmap/2360 is trying to acquire lock:
 (slock-AF_INET6){-+..}, at: [<c05b36ee>] sk_clone+0xd4/0x2d8

but task is already holding lock:
 (slock-AF_INET6){-+..}, at: [<dfb8e4d1>] tcp_v6_rcv+0x327/0x736 [ipv6]

other info that might help us debug this:
1 lock held by setxkbmap/2360:
 #0:  (slock-AF_INET6){-+..}, at: [<dfb8e4d1>] tcp_v6_rcv+0x327/0x736 [ipv6]
