Mmmh, the CPU load is the cpu load of the process and all it's child
processes.  Of course one process it self can't go beyond 100% but
with all it's children it can go up to number_of_cpu*load.

My idea of 100% _CPU_ load is, one process occupies one _CPU_
completely.  So if a process and a child does take each a full CPU I
would see it as 200% _CPU_ load -> If the system has two CPUs in
total that would make 100% _SYSTEM_ load.

Why do I want this... I don't want to find out how many processors a
system has.  Linux would be easy.  But the first difficulty it
Solaris... last and definitely least FreeBSD.

Compromise solution: set numcpus = [n]
If omitted numcpus is 1.  What do you think.

Grrr... I just have looked into Google "sysconf(_SC_NPROCESSORS_ONLN)"
gives me the number of CPUs which are online.  For Solaris it should
work, for Linux it might, for FreeBSD I don't know. (-:

Do you want always 100% as max?
