	* FCatch.java (Blocker): Added. TaskObserver.Instruction blocking
	observer class.
	(signalObserver): Added. Add the same SignalObserver to each of the
	Tasks.
	(generateStackTrace): Decrement the numTasks counter.
	(removeObservers): Removed.
	(handleTaskBlock): Added. Switches on the signal value to appropriate
	update the stack trace StringBuffer. If all the tasks of the process
	have passed through, prints the StringBuffer and unblocks all the tasks.
	Fixes #3932.
	(CatchObserver.updateAttached): Initialize the global SignalObserver if
	it is null, and add to each task that passes through.
	(CatchObserver.updateTerminating): Removed eventloop stopping code.
	(CatchObserver.updateTerminated): Requests a stop from the eventloop if
	all the Tasks have completed stack tracing and are unblocked and
	terminated. Fixes #3932.
	(SignalObserver.updateSignaled): Assign some global variables from the
	signaled Task. Moved switch statement and stack trace calls to
	handleTaskBlock(). Block each of the threads of the process with an
	InstructionObserver. Fixes #4092.
	* TestFCatch.java: Added some more fields reflecting the above updates.
	(FCatchTester.Blocker): Added. Blocking TaskObserver.Instruction observer.
	(handleTaskBlock): Added.
