Christoph is, of course, correct here. Something that is confusing 
about HTCondor is that we informally call the schedd a "queue", or that 
it holds a "queue" of jobs, but HTCondor does NOT, in a mathematical 
sense, schedule in a strict queue, for a number of reasons. Jobs that 
worker nodes prefer may "jump the queue", jobs that match now will start 
running before larger jobs that may only match on machines that are 
currently busy, etc.
