[PD-dev] more on external perform question

[ben at ekran.org]

Hey Scott,

I've made a couple of externals that "act" continuous but I've always just
set up the methods so that they are called by a bang to the object from
the outside...

This way you can control how often you want to poll the HW (or whatever)
from PD... Or did you need faster than 5ms updates? Seems a little
over-kill for a head-tracker....
