Log Message:
Changes 5.0.1:
* We believe that we have resolved most of the problems
  concerning canceled or failed jobs being "stuck" in the
  Director.  There is one outstanding problem in the SD when
  canceling jobs that we will fix in the next major release.
  If you see jobs that seem to be stuck, in general issuing
  a cancel command in bconsole should now make them go away.

Directives:
* The default for "Allow Duplicate Jobs" has been changed from
  no to yes.  If you use this directive, please check your
  conf file, and note the next two items!
* AllowHigherDuplicates disabled. It did not work as documented
    and was confusing.
* New directive "CancelLowerLevelDuplicates" See New Features
  section in the manual.
* Truncate on Purge rewritten.  See New Features section in the manual.

* Bug fixes

* Ensure SD asks for help when looping even if poll set.
* Fix three-pool regress bug
* This version fixes an issue where the console window would start out
  docked. It is fixed by initiating the variables in the Pages class wi
  constructor.
* Fix make_catalog_backup.pl fails when catalog db is on other host
