That's a lot better, thanks.  In fact, this patch was good enough to
let the TEST-CREATE test run without crashing the GC.  (It's still
not good enough though; the test in BLOCK-ALIVE-P is too simple,
because it assumes that all versions except the most recently saved
one are dead.  That will work for simple cases, but I think there
are cases where this assumption is not correct.)

If you feel like following this path, you could now try to keep fixing
TEST-LOAD until it doesn't crash anymore.  And then TEST-UPDATE ;-)

Committed (you can subscribe to rucksack-cvs if you want the follow
the CVS commits, by the way).
