env_max_procs uses this order of precedence to get a
1. Various resource managers
2. If a global hostfile was specified
3. If a global hostlist was specified
4. If a global max_np was specified
Shouldn't 4 be at the top of the list?
I'm doing single node testing, but the fact that I have only
one node listed in hostlist causes env_max_procs to return
"1". I'd like to override the 1 value with the number of
CPU's on the single node I'm running on.
