	I have just begun to look at System V semaphores.  Needless
	to say, the Bell documentation leaves much to be desired,
	and we do not have System V up and running.  Can anyone
	help me with the following:

	* What's the benefit to such a complex data structure?  Does
	  it solve some special problems elegantly?  What's the 
	  performance?

	* Examples: dining philosophers, consumer-producer, etc.?

	* What is SEM_UNDO all about?

	Any comments or references to published literature would be
	appreciated.  Thanks.
