Is there anyway to force a machine to become unclaimed when jobs
finish? would this significantly affect throughput when the farm has
only one user with many jobs?
There is no way to do this, but the feature you want will be in 6.7.x
(probably 6.7.1). Your solution which allows preemption during the
early stages of a job is the best workaround that I know about.
Unfortunately, you don't want to do that for a certain class of
"critical" jobs, so those will be problematic.
I should mention an additional clever but expensive workaround that some
people came up for preventing critical jobs from being killed while
still allowing preemption to happen: they set PREEMPTION_REQUIREMENTS to
allow preemption during the first 10 minutes of execution and they make
their job sleep for 10 minutes (plus a few for safety) on startup.
