from preamble:

"Change Set:		ExplorerSpeedup-efc
Date:			21 July 2005
Author:			Eddie Cottongim

Makes scrolling smooth in SimpleHierarchicalLists faster by using a
binary search to only draw visible elements. TransformMorph has also
been given this ability through an extension. IndentingListItemMorph has
a minor change to prevent an unnecessary copy of its owners submorph
collection.

The object explorer remains slow to open initially.

Try it out with 
(1 to: 10000) explore.
