	I want to avoid that executing "Optimize World" before doing an incremental
	disk save makes the saved world a lot bigger.  I don't know how I have to
	build the parent world (a complete disk save).  Do I have to call both
	si:full-gc and "Optimize World", if yes, in which order?  Is there something
	else that I have to do?  

[...]
					 and do an Optimize World before an
    incremental save.

Every ancestor world has to have been Optimized.  If not, the result
will be much larger.
