Runtime: wx.app.mainLoop and twisted reactor now share main thread with runtime.Worker.
This fixes exception when invoking python interactive shell from Runtime's tray
icon right-click menu.
Probably a consequence of wxPython upgrade, together with initial bad idea to
move wx.app.mainloop in non-main thread.
