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.
