Need book on Unix systems programming

[Greg Skinner]

Does anyone know of any book(s) which deal with Unix systems programming?  I'm
not talking about C programming books, but books which give examples of memory
management schemes, dealing with pipes and forks, process scheduling, etc.  If
there are a lot of responses I'll post them to the net.
