Exactly. And, by default, all jobs submitted by dagman add a
keep_claim_idle = 20 to the submitted job. This allows the schedd
to hold onto the claim for subsequent jobs from the user, even if
they haven't been submitted just yet. In many cases, this
dramatically improves the throughput of dagman. This also means
that on a condor hold, the slot that was running the job will
stick in Claimed/Idle for a bit.
