Incremental World is a nice feature, especially when you are dealing
with huge worlds. 

I have been using this facility on the Symbolics Lisp Machines and have
discovered lately that this feature is not available on a new lisp I
am using: Sun Lisp 3.0 (Lucid). 

Considering that a SunLisp Full World is approximately 10 Megabytes (5
Mega for the basic world), it is very expensive to disksave any new
stuff you built on it...

Is it "almost impossible" to do? Or is it just that nobody thinks that
it is necessary at this point?

I have the feeling that this must be VERY difficult to implement
because you need lot of book keeping, but it does not cost anything to
ask...
