Python 2.6, multiprocessing module and BSD

[YouCanCallMeAl at gmail.com]

It seems that the multiprocessing module in 2.6 is broken for *BSD;
I've seen issue 3770 regarding this. I'm curious if there are more
details on this issue since the posts in 3770 were a bit unclear. For
example, one post claimed that the problem was that sem_open isn't
implemented in *BSD, but it is available on FreeBSD 7 (I checked). I'd
be willing to help get this working if someone could point me in the
right direction.
