Basically you get a backup between consistent states.  My concern is
more along the lines of dumping images that contain passwords and
session keys even though there are no explicit references to them.
Given that fullGC() is called prior to a snapshot, the unreferenced
objects should vanish unless the GC is conservative.  I should learn
to UTSL a touch more often before asking stupid things.
