Hi--

	Now that Squeak supports ensured behavior, Semaphore>>critical: should
ensure that the receiver ends up with an excess signal, no matter what
happens while evaluating the critical block (e.g., an unhandled
exception). Something along the lines of:

***

	self wait.
	^aBlock ensure: [self signal]

***

	And is Semaphore>>critical:ifError: really necessary anymore, given the
current exception-handling system?


	thanks,

-C
