If there are any other observers installed e.g., a CodeObserver, the task won't
unblock after calling requestDeleteInstructionObserver; requestUnblock must be
called too. See frysk.rt.RunState.run.

#4057 is apparently a result of the combination of
requestDeleteInstructionObserver() + requestUnblock(instructionObserver).
Can be observed by trying to 'continue' almost any non-debuginfo program in the
sourcewindow.
When working with step-over and step-out in RunState, I did not notice this
bug, but the difference is that in that case the InstructionObserver was being
deleted from CodeObserver.addedTo(), instead of when both were fully blocking
the Task.

My little test program:
int main (int argc, char **argv)
{
int i = 0;
while (1)
{
if (i > 0)
i--;
else
i++;
}
return 0;
}
I use fhpd to attach to this running program:
attach test1 0000
break test1.c 10
go
Without the call to requestUnblock the process won't continue.
