All new processes stuck in "flstik" state

[Rumko]

Most of the time when I see processes in flstik state, the machine recovers,
but have managed to find how to reproduce the situation, where all new
processes get stuck in flstik state (even ssh-ing into the machine creates a
new sshd process which gets stuck in flstik state and won't continue, can't
login locally, etc.).

The machine has /boot UFS and / hammer with several PFS' (done using
the /usr/share/examples/rconfig/hammer.sh, but my /var/tmp isn't a PFS, but a
softlink to /tmp).

If I run http://pastebin.ca/1279548 (with http://pastebin.ca/1279549 as the
pkgsrc.img.label) 2, sometimes 3 times, all new processes get stuck in flstik
state during installworld.
Panicked the machine and uploaded the cores (the first time it happened i
panicked the machine and made the memory dumps and after succesfully
reproducing the situation i did it again) to
