Yes: all the classes registered with the startup list get notified by
calling their #startUp: or #startUp method. The parameter to startUp:
indicates whether the image is restarting after a snapshot.
you do this:
Smalltalk addToStartUpList: SomeClass.
later the system calls:
SomeClass startUp: true (if resuming after snapshot)
SomeClass startUp: false (if starting fresh)
