This comes up every now and then I always do my best to shoot down the idea of
implimenting this as an environmental variable.

One day we would like to have variable-sized jobs. If nodes/cpus are added or
removed while a job is running, then that env var can not be updated.

If implemented, it must be done with the count in a file and the name of the
file is in an env var. This is exactly like $PBS_NODEFILE.

If "procs" gets traction, then I'm sure this can be done with procs.
