The default number of slots will be the number of "cpus" assigned by
Torque, which with every version of Torque I've seen, is the number
of times that host is listed in $PBS_NODEFILE (although we get the
information through a different mechanism).
It appears that we don't have a good way to feed that information
back to the user through a debugging flag or anything like that,
although we probably should add that feature at some point.
