Deleting an Instruction observer should unblock the task if it is the last blocker.
deleting the InstructionObserver *does* unblock the task, that's how I run the
task in the sourcewindow normally - but it doesn't seem to unblock the task when
there's a TaskObserver.Code added to the task as well
Which is why I asked if requestUnblock should be the only way it unblocks in
that case; because it works that way
the cycling instruction stepping I mean
I should have also mentioned that this scenario reproduces #3500, whereas having
just the TaskObserver.Instruction added to the task (as was the case in that bug
originally) appears to not kill the process anymore. Likely that the problem was
better hidden by the kernel update rather than solved.

Fixes bug #3571
* frysk-core/frysk/proc/TestTaskObserverInstruction.java: Don't
explicitly unblock before deletion of observer.
* LinuxPtraceTaskState.java (BlockedSignal.handleDeleteObservation):
Explicitly unblock observer.
This now enables to run a testcase that actually describes comment #2 (which is
