Wait Until Process Completion

The following worked correctly in Tiger.

	repeat
		delay 1
		do shell script "ps -p " & pid --<<<<
		if not (the result contains pid) then exit repeat
	end repeat

But, in Leopard, the line marked --<<<< errors (= 1) and my script stops.
So, I replaced it with ...


	repeat
		delay 1
		try
			do shell script "ps -p " & pid
		on error
			exit repeat
		end try
	end repeat

and now my script is again working correctly. But why?
Something has changed its behavior.
Does anyone know what's going on here?
