The callbacks to be dispatched are supposed to either set a simple flag that 
triggers action within a module/widget, or to post a message into the wx 
message queue. Both these things should be thread safe in themselves. Complex 
GUI operations are not suited to be triggered *directly* (vs via message 
queue) via a dispatcher callback, though nothing (but stupidity) is stopping 
you from doing it.
