I too have wondered about this and have had success with the following
experiment:
	I have a Midi processing box that interrupts the host if told to
do so. The service routine does a bunch of parsing and then calls a C
routine which increments a global variable. This is a fair amount of
overhead. What I have done is fire up a fprintf loop out to a file
and then let the hardware interrupts fire away. My initial experiment
worked, but I don't know if I am playing with fire. My experiment was
writing to hard disk. Anyone know anything more about this?
