> The killstaleprocesses() routine in shell.py expects pidfiles to have a pid value encoded in the name (ie the name is of the form PIDVALUE.pid).
> However, ambari-agent writes the file "ambari-agent.pid".
> killstaleprocesses() should either handle both forms for backward compatibility, or should only handle the new form.
