Lightweight processes

[alan dare]

	Section 14, volume II of the Programmers Guide introduces shared
resource groups as "...a lightweight process facility". What are the
criteria for a lightweight process? What advantage do they have over
processes communicating through shared memory? I'm not looking for "one
process can open a file ...". In a real time environment with no file I/O
how does it improve performance and how do I know if my process will fit
into the "lightweight process mold"?

Thanks for any help
