This the classic control inversion problem, when two top level
architectures both demand to run the event loop. From memory,
Tcl is very good in this area, since it is actually designed to 
support event loop merging, which of course was dictated by the
need to handle GUIs as an extension.

More recent offerings such as Gtk seem to have taken a massive
backwards step.
