Given Brian's extensive involvement in GDM I don't see it becoming
linux only any time soon :-).

We also have Joe Markus Clark posting FreeBSD patches fairly regularly.

Right, but reset_seed would just do what g_random_new does when
generating the initial seed.

I mentioned that earlier, I think.  One reason I rejected that idea
(aside from you wanting us to use /dev/urandom directly) was that the
glib api docs don't mention or guarantee the initial seed is 128 bits.
 I didn't think it would be a good idea to depend on an undocumented
implementation detail.
