Noticed this yesterday.

The setup-assistant appears to doing an instant apply - attaching to and hanging
the processes - before the user has indicated that they are finished.  Several
problems I can identify here:

- when re-opening a session, processes are being attached _before_ the user has
confirmed the choice
As I pointed out in another thread, the operation and consequence here is
non-trivial, so the user needs to be given the chance to confirm the selected
processes before going further.  The problem/consequence is easily seen by:
create a "bash session"; quit frysk; from bash start frysk in the _forground_;
open the "bash session" bringing up the process-picker; try backgrounding frysk

- instant apply works when there is instant visual feedback
Since the monitor/debugger is not yet displayed (and no please don't start
displaying it), there is no visual feedback, and no reason for the apply.
