Given the stability and portability problems we have been encountering
with PTL2, are there any objections if I switch glib2 over to pth?  (For
those who want to debug or play around with PTL2, I will provide a
USE_PTL2 option that can be set in /etc/mk.conf).

  I will perform some more tests, but all programs I have tested so far
work out of the box with pth.  Not only that, bus also programs like
gice or gtk2-pan than used to crash on me pretty often, now seem to be
running much more stable with pth!

  This will hopefully also allow us to finally get working GNOME2
packages.

  Cheers
