there are no timestamps available on input events, although that would 
be really nice. you may want to 'block' the mousemotion events, since 
they can add up pretty fast and fill up sdl's not-too-large queue.

pygame.event.set_blocked(pygame.MOUSEMOTION)

if you never need the mouse motion events you can just leave it blocked. 
otherwise you can call set_allowed() when you are ready to start working 
with the event queue again.

hopefully there is some sort of timeout or polling method you can use 
for the lpt trigger. otherwise the graphics window will be a bit 
disabled while waiting for the trigger to happen.
