Tim, I had your same symptoms (as far as "delays/jerkiness" can go):
when using the USB external mouse and leaving it in *some* positions,
the whole system was paused until I move the mouse even a little bit, at
that point all "missing events" (i.e. all keypresses that didn't produce
any output, or also all screen updates) are shown in fast-forward (e.g.
the Firefox spinner of a loading tab was stopped until the mouse moved,
and made the 3 missing turns rapidly, then all to normal). When the
mouse was left in other positions, no problem was shown.

After Googling your message I commented-out the AllowEmptyInput line in
my xorg.conf and now both internal touchpad and external mouse work
perfectly and don't "halt the event queue" (or what it was) anymore.

I still wonder the reason behind this behavior but as long as it's
working, I won't complain.
