I've picked CentOS 5 for a research project and have been up and down centos.org looking for descriptions of its guts, processes, thread handling, kernel etc.
One of the topics is "processes", that is, how it handles multi-threaded system, etc.
I know CentOS and RH are close and most of the CentOS manuals point to Red Hat.
Any URLs that you might think is useful is exponentially appreciated.
Cheers,
Dan
