i don't know what is up yet, but maxv changed this file recently.
i wonder if there was/is something special about either SVS here,
or fpu_lwp_fork() it's triggering on.  i don't see any attributes
that should apply here.. guessing SVS as it is the only conditional
compile there that should matter, but i still don't see anything
that actually points to it.

Maxime?
