Summary: Python crash on __init__/__getattr__/__setattr__ interaction

Initial Comment:
The following code causes [Mac]Python 2.3 process to crash 
(Bad!) rather than raise an error (good) when creating a new 
instance of Foo:

class Foo:
	def __init__(self):
		self.x = 1
	
	def __getattr__(self, name):
		if self.x:
			pass # etc...
	
	def __setattr__(self, name, val):
		if self.x:
			pass # etc...


(See <http://freespace.virgin.net/hamish.sanderson/
HTMLTemplate-0.4.0.tar.gz> for a working example plus general 
solution to the referencing-instance-var-before-it's-created 
paradox that threw up this bug in the first place.)
