As far as I can tell that function ends up getting called with force == TRUE
once for each process that calls GetDesktopWindow() (plus once for explorer.exe
itself). The call chain goes:

GetDesktopWindow()
-> retrieve top_window from server, call user_driver->pCreateDesktopWindow()
-> X11DRV_CreateDesktopWindow()
-> root_window is not yet initialized; call X11DRV_init_desktop()
-> set virtual desktop handler, call X11DRV_DisplayDevices_Init( TRUE )

The code organization here is too unclear for me to tell where the fault lies.
