An event-driven architecture already exists; namely Morphic.  It 
currently interfaces with the polled Squeak interface through 
HandMorph>>processEvents, which continuously generates Morphic events, 
but it should be relatively easy to push the Morphic event interface down 
through to the VM, generating these only when the actual action occurs.
