Probably more of a stress-test edgecase; but when trying to open frysk on the
following program from the GUI, it appears to hang for a few seconds, and then
fail with the following:
java.lang.RuntimeException: destroyed
at frysk.proc.LinuxPtraceTaskState$16.handleAddObservation(FryskGui)
at frysk.proc.Task.handleAddObservation(FryskGui)
at frysk.proc.TaskObservation.handleAdd(FryskGui)
at frysk.proc.LinuxPtraceProcState$Attaching.allAttached(FryskGui)
at
frysk.proc.LinuxPtraceProcState$Attaching$ToOtherTasks.handleTaskAttachCompleted(FryskGui)
at frysk.proc.Proc$4.execute(FryskGui)
at frysk.event.EventLoop.runEventLoop(FryskGui)
at frysk.event.EventLoop.run(FryskGui)
at frysk.gui.Gui$4.run(FryskGui)
at java.lang.Thread.run(libgcj.so.7rh)
The test program endlessly creates and destroys threads.

Thread test
gcc -O0 -g -o thread_test -lpthread thread_test.c should do it.

The problem here is that frysk.rt.RunState throws a hissy fit when it sees any
addObservation failing:
public void addFailed (Object o, Throwable w)
{
w.printStackTrace();
stateProc.requestAbandonAndRunEvent(new RequestStopEvent(Manager.eventLoop)\
);
System.exit(1);
}
The TaskState really cannot help that the request for an observer addition was
done just at the moment the Task was about to be destroyed.
Is there anything the TaskState can do to help RunState recover in this case?

As a workaround for now I just treat Tasks falling through addFailed() as if
they did an updateExecuted() so they disappear from the list of Tasks being
waited on.

isnt System.exit(1) kind of harsh.
It sounds like TaskState had a good reason for the add to fail, so RunState
should handle it and move on.

Can I suggest using never using System.exit in any case from the UI? Suggest using
Gui.quitFrysk()
which is a static method. It shuts down the GTK eventloop with mainQuit.

Well this is in RT so potentially it could be just fhpd running, but the
System.exit was just an oversight - there are certainly better ways of handling
that problem than just quitting. I'll look into a better solution.
