I haven't looked at the code personally but I would imagine the objects 
only exist through reference from other objects. Once they are no 
longer referenced, Python will garbage collect them and free the 
memory. For example:-

Class Player:
	...
Class Round:
	...
while True:
	# Start new round
	nRound = new Round()
	nRound.addPlayer(new Player())
	# MemLeak (C) EA
	gobble.append(" ")
	# More game stuff
	# End round
	del nRound

Since the player is only ever referenced through the round object, once 
the round is removed, so too is the player. This would explain why 
there's no "del playerX" statement per se.
