[Nottingham] Process CPU and memory usage?

Martin,

Not sure what you mean? If you want to sample the stats at regular 
intervals then just call ps/pstree repeatedly with a sleep between calls.
How frequently do you want to sample?

If you look at their source, they actually share a library of functions - 
in Fedora 9, the procps rpm contains /lib/libproc-3.2.7.so. So you could 
write your own routines.

Patch the kernel?!?
