A number of people, including Ray Buhr and Grady Booch, advocate the
use of "timing diagrams" in the engineering of software. The timing
diagrams they show typically have various operations (functions) along
the y-axis, and monotonically increasing time along the x-axis. I have
been told that such timing diagrams are quite common in various types
of engineering.

I have two questions:

	1. Are there any _general_ references for "timing" diagrams? 

	2. All the timing diagrams I have seen are for sequential
	   processes. Are there any special considerations, or changes
	   in form, for concurrent processes?

If I get any responses, I will post a summary to the net.
