[PD] Timing the message processing?

[Larry Troxler]

Is there a way (or could there be made a way) to time how long it takes
for PD to do its message processing when an event arrives?

In my case, I'm interested in measuring how long my scheme externs take
to run (which I fear is longer than is good), but of course, such a
feature might be usefull for anyone who is running a complex message
process in an extern and wants to know if they run a chance of missing
the next DSP deadline.

Just to be clear, I'm not talking about DSP processing time, but
strictly the message passing time (which is intermittent, but might take
a long time when it happens).
