ObjectMemory class >> snapshot: does not provide any way to determine
whether, at the return from #snapshot:, we are running in

1. the parent, just after the save, or
2. the saved image, just after the load

A good solution to this would be to return some indicator of which
image-instance we're running in from #snapshot:.

Given such an indicator, we could build a #snapshot:andQuit: message, a
la Squeak, which would provide a convenient way of saving a snapshot and
quitting, without having to jump through hoops on resume to determine
which actions to take next.
