My suggested fix did not work.  My current solution, included in the
upcoming patch post was to remove function xenfb_resize_screen() and
restored xenfb_thread() to it's original state and put a lock around the
event queue.  Resize event is now directly sent from xenfb_set_par().

You might want to have a look at that code.
