Note that Gtk is not thread-safe in the first place. The only
supported way of working with threads is by using one dedicated thread
for Gtk related code and otherwise using g_idle_add and friends to
delegate calls to that dedicated thread.

Incidentally I can confirm that using WebKit (Gtk) in different
processes combined with pipes works perfectly, although I don't
actually have a use for threads. Such a setup actually improves
interface responsiveness, if that is your intent.
