the startd only evicts jobs that use "too much" memory if you
configure it to be that way.  for example, your PREEMPT and/or SUSPEND
expression must have a clause like this:

PREEMPT = (...) || (TARGET.ImageSize > Memory * 1024)

unfortunately, ImageSize is in kbytes, while Memory is in mbytes. :(

so, if you don't have anything like that in your PREEMPT and SUSPEND
expressions, Condor will happily let your job keep running, even if
it's using more RAM than it asked for.
