1.)Smalltalk does support multiple inheritance.  The framework is still in place
in Smalltalk/V in class Behavior.  There are third party add-on 
products for MI on Smalltalk/V.  There are a number of simple "mixin"
examples that one can cite as arguments for MI but the real problem 
seems to be the added complexity of MI from a conceptual standpoint 
makes real world applications using MI difficult to manage.  A. Borning
and D. Ingalls documented this in "Multiple Inheritance in Smalltalk-80".
Proc. of National Conf on AI, 1982.

2.)There are several library management tools for Smalltalk.  They
range in price, functionality and utility all over the spectrum

Low end 

	Carleton APP Manager- part of Digitalk Goodies

medium 
	Instantiations App Manager for ST-80
	Zuniq App Manager for Digitalk ST and 
	Coopers&Lybrand Softpert Application Manager for Digitalk

high end
	Object Technology International ENVY Manager for multiuser 
	online Smalltalk CMS and library management.

One of these tools will do the job depending upon your Smalltalk library 
management needs.

3.)Some very impressive things are happening with Digitalk's Smalltalk/V-PM
running on OS/2 that warrant qualification as ST supporting true preemptive,
multithreaded multitasking.
