Subject: Blocked in keyctl(...) ???

Hello,

Sometimes, my applications start "locking": nothing happens anymore, can't
kill them... 
I manage to strace them, to find that they are executing the following
syscall:

13686 keyctl(0x1, 0, 0xffffffffffffffff, 0x7fa90fd6a2c0, 0

and that syscall never returns.
I don't have anything interesting in the system logs, and that happened to
me while using all the 3.3-rcX up to rc5 (I've just rebooted an rc7).
Can't tell if that occured pre-3.3 or not.

Does anyone know what could cause something like that ? 
Should I fwd my .config ?

Best,
Paul
