Does anyone know why it takes so long for a session or process to be
     cancelled?  I just waited a couple hours for a process to finally
     clear out and while it was hanging, other sessions against that node
     would not run.  The same thing happens with sessions.  If a command is
     entered wrong and then you cancel the session, it still shows up as an
     active session and it does not appear that the next session will start
     up until the previous one is gone.

     Thanks!
