Optimize World and si:full-gc

[andreasg@boulder.Colorado.EDU (Andreas Girgensohn)]

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?  

How do I build a complete who-calls database if I intend to do an "Optimize
World" later?  Do I call si:enable-who-calls with the argument :all,
:all-remake, or :all-no-make?  Is it necessary to call
si:compress-who-calls-database if I execute only "Optimize World" and don't
call si:full-gc?
