[erlang-questions] Measuring the overhead of various port driver approaches

I would like to measure the overhead of receiving data in the output  
callback vs. outputv as well as the overhead of various ways of  
returning data.

Would it suffice to send now/0 down to the driver, have the driver  
send back the timestamp returned by driver_get_now and then grab now/0  
once again?

	Thanks, Joel
