	This file implements the second test for the Haiku BMessageQueue code.
	It tests the Add Message 1 and Find Message 2 use cases.  It does so by
	doing the following:
		- creates numPerWhatCode * numWhatCodes messages and puts them on
		  the queue and the list
		- searches for the xth instance of a what code using FindMessage()
		  and by searching the list
		- compares the result of the two
		- there are many cases where FindMessage() returns NULL and those are
		  checked also
		- it does all searches for all the what codes used plus two not
		  actually used
