LastMatchName0 = "some-gatekeeper-ad-name"
LastMatchName1 = "some-other-gatekeeper-ad-name"
..
LastMatchName0 will hold the most recent match name. The list will
be rotated (LastMatchName0 will move to LastMatchName1, etc) with a
max length
defined by match_list_length in the submit file, which has a default
value of zero
(i.e. don't keep this list in the job ad by default). The idea
of this list is to allow the job to prefer to match with a different
resource (or the same) as in the past.
Then make your requirements expression refer to these matches.
