I've seen the same thing.  I was downloading a file while trying to do
something else and the system got *extremely* slow and jerky, and the 
download kept failing.  I was running some program (I can't remember which
one now) that was number crunching or rendering or otherwise using every 
free cycle, but it was running at 0 priority, so I don't know why it would
screw-up the inputdevice.
