I expect the real condor experts know more than me, but I should have 
thought not. Once the HTCondor job ends, that's it, I think - no more 
book keeping (it might be better if the script did not detach from its 
Java payload until the end.)

Again, as far as I know, I think HTCondor would have no simple way to do 
direct book keeping for that.
You can probably do things like have the machine sense its system load 
or memory usage and refuse to start jobs if necessary (see START 
expression) or put a requirement in the job to only match with machines 
that already have low load or plenty of free ram etc. But there would be 
nothing to stop these other applications continuing to start jobs after 
then.
