No, it's not the currently running job - it's the machine that the
negotiator is considering for preemption. And remember, 
PREEMPTION_REQUIREMENTS must become TRUE for the new job to claim 
the machine (it's sometimes hard for me to keep it straight)

It is everything available in the VM ClassAd. If you want something from 
the job ad, you have to export it into the machine ClassAd using
STARTD_JOB_EXPRS.

One caveat - STARTD_JOB_EXPRS is not really VM-aware - so if you export
it from one VM it winds up in the ad of every VM on that machine.
