It's because the 3.2-stable kernel doesn't currently support forks with
shared address space.  It appears that this has been fixed for -current,
but I don't know when, if ever, 3.2 will be fixed, since it's been
broken since at least March 2.

It looks like Julian Elischer was the last person to commit anything to
sys/kern/kern_fork.c in -stable, so he may know if there are any plans
to fix this before 4.0 is released.
