Description Chris Moller 2006-06-07 17:26:42 UTC 
1. Start forker in infinite loop mode (a new capability since the initial
forker.c I sent out last night).
2. Select the parent forker proc in druid.
3. Check the fork, task terminating, and exit notification observers.
4. Press finish.
5. "Frusk Core Errors" window appears:
Frysk Core has reported the following errors

{frysk.proc.LinuxProc@1245050,pid=18824,state=Attaching.ToMainTask} in state
"Attaching.ToMainTask" did not handle handleTaskDetachCompleted

Comment 2 Mark Wielaard 2007-02-02 13:18:10 UTC 
Seems to work fine here. But note that I didn't know what arguments to give
forker and that there isn't an exit notification observer anymore in the gui.
Running it with "./forker 0 24" and selecting the Terminating and Fork observers
gives lots of events.
