I like this. Its also easier dependency-wise, as we don't need to make
libglib.so link in libgthread.so (which is kinda weird and possibly
problematic due to the circular deps), just libgobject.so.

This would mean that for Gnome 3.0 we'd guarantee that threads are
always initialized. Of course, it also means we really have to land the
gobject performance fixes for threaded stuff, but we want to do that
anyway.
