Try the original recipe from the python cookbook. It works for me across 
platforms. I'm using 80ms for the timer. As Itamar put it, it's not perfectly 
reliable and usually needs tweaking with the timer. I found values between 80 
and 120 ms to be working.
Writing a real reactor is at least very complicated if not impossible. Wx uses 
the internal even loops of the platforms underlying graphical toolkit, so 
this means the whole thing works differently when using GTK or GTK2 or 
Windows Controls or Mac... etc. So the reactor code would have to be smart 
enough to detect the platform and hook into the graphical system's eventloop.
Windows uses multiple event loops for modal dialogs, so whenever you open a 
modal window on windows a secondary eventloop handles that one window and the 
primary eventloop is stuck until the modal window closes. Same goes for 
pulldown menues.
