But please note that `nice' doesn't limit a process's CPU time per se.
By using it, you're telling the kernel that this process should only
get CPU cycles when there's no other process that might want to have
them.

On an otherwise idle systems, it doesn't really make a difference.
SIMH will run on 100% simulating the guest OS's idle loop (or real
work, though.)  That is, you won't see power savings on the host
system by nice'ing SIMH down. You may get that once you have useable
idle loop detection.
