That's not a problem, because threads will most definitely not solve  
this problem anyway. Mouse positions are only going to get updated  
when the event queue is pumped, and besides that you'd lose *more*  
mouse information by calling get_pos than by inspecting each  
individual event since it just returns the last mouse position that  
SDL knows about, rather than each individual event.

In this case, there's nothing you can do except interpolate --  
Windows is coalescing some of those events (and I would expect other  
platforms to do the same). Using a bezier curve to interpolate  
between mouse positions usually produces something reasonable looking.
