they are the in the same units as normal linux resource limits. that's 
why it is not adding its  own mechanism but reusing existing one. most 
of them are in bytes, unless obviously otherwise, like cpu time (in 
seconds or ms ?) or process limits.

good values are all up to you and your system, nobody can predict your 
needs. for sure set process limits per user to protect about stupid 
fork bombs, say to 100 or mayby 200 (guesing only). also limit memory 
usage. basically all documentation you are able to find about normal 
linux resources limiting aplies here as well.
