Talking with customers and users, it sounds like there's a real need for a way
to coschedule jobs to take advantage of a shared large data set.  One example
solution might be a -follow switch to qsub with similar semantics as -hold_jid.
 Running qsub -follow 4 job.sh would send job.sh to wherever job 4 went.
Another option might be more explicit support of data sets using resources.
