Well, that's some of what's needed. I notice this code is also being
sloppy about whether block numbers are signed or unsigned, which means
it'd probably misbehave on relations exceeding 2^31 blocks. I have
a patch in progress to clean all that up, though I'm still working
on the strict-aliasing part.
