Autotest is too late and also not nearly rigorous enough for what you're 
trying to catch.

Here's how I propose we tackle this.  This patch adds a -dump-savevm 
option that takes a version.  It spits out all of the fields we save for 
a particular version (well, not really, but it should).  We also can add 
type information.  The idea is that we'd write a simple test case (using 
gtester) that ran through and dumped the schema for each version.  We'd 
store the schema's in the tree and the test can compare old schema's to 
the current schema to check for failure.

This was thrown together in just a few minutes.  I'll try to put 
together something more complete later today but I wanted to share this 
before the call at least.
