Ben should be able to help you with that.  I unfortunately know doo-dah
about linux.

Yes, there's a very good reason.  I'm a lazy bum :)

I've been putting off worrying about memory leaks (which that is an example
of) until later.  There are also a fair number of unmatched pr_mallocs.

Note that when you make or get responsibility for a new object you may
del_unlock it after putting it in a containment hierarchy rooted in
global_objects, or you may leave it del_locked while you want it preserved
until you del_unlock it later (the equivalent of doing a pr_free to a
pr_malloc).  So it is legal to not del_unlock a new object if you are sure
it will be del_unlocked later.

P.S. You will discover that the garbage collector in the other thread is
quite aggressive. If you accidently do del_unlock() too early it is
surprising how quickly that obj will dissapear out from under you.  You'll
get quite nasty errors.
