           Summary: CommandLineExec needs ability to kill spawned process
           Product: Kepler
           Version: 1.0.0beta3
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: actors

Many times when authoring/debugging a workflow, the process spawned by the
command line actor runs infinitely.  It would be good if the CLE actor kept
track of the process id and could kill the process either with a special user
function or when you click the stop button.  Right now the only way to do this
is to either kill kepler or to figure out which process is hung and kill it
manually.
