It doesn't look like this is fixed in condor 7.0.0 either.  I have 8 
slots on the node, and new jobs keep arriving.  Jobs take ~8 hours to 
complete, and I have quite a few jobs sitting idle waiting for slots, so 
the system is likely never to become idle.

Still no luck.  No jobs got removed, and new ones keep getting started.
