HTCondorWiki: How To Avoid Job Restarts

-Note that this does not _guarantee_ that Condor will only start the job once.  The =NumJobStarts= job attribute is updated shortly after the job starts running.  Various types of failures can result in the job starting without this attribute being updated (e.g. network failure between submit and execute machine).  By setting SHADOW_LAZY_QUEUE_UPDATE=false, the window of time between the job starting and the update of =NumJobStarts= can be decreased, but this still does not provide a guarantee that the job will never be started more than once.

This policy is therefore to run the job at least once, and, with best effort but no strong guarantee, not more than once.
