I don't have any answers, but I am very impressed by this kind of testing
and grateful for the contribution.  My thoughts on evil experiments
focused on timing and component failure.  Obviously, resource limits 
are extremely important as well.

I suppose ideal behaviour would be to refuse to create a snapshot when
memory is "low".  But defining "low" can be tricky.
