No. Snapshot is when you just say:

Smalltalk snapshot

or the equivalent:

Smalltalk snapshot: true andQuit: false.

or choose "save" from the menu. When you do this, all shutdown 
registrants are first told

shutDown: false

then the image is saved, then all startUp registrants are told to

startUp: true

We do this so that we don't save the image in a start that can't be 
restarted easily.
