It seems to be t150 in the XMG-GenI integration demo

In the debugger, it happens at iteration 142 (or 141?)

I can confirm that GenI 0.17.4 makes it through this.
So either this is a regression or something else has changed that reveals the error.
If I understand correctly, this bug means we're trying to register more than one substitution for a variable, which doesn't make sense because normally once you've registered a substitution that variable is gone. I think this means that we're basically just failing to propagate substitutions somewhere...
This makes me want a better abstraction over unification.

Cool! This may not be a unification bug after all, but a repeated adjunction.
Why are we getting this?

Fix #31 - unification bug cause by failure to propagate.
We do top and bottom unification after adjunction; however, the
nodes that we were doing unification on did not have the latest
substitutions from the adjunction test applied to them.I'm still not sure why this is a regression from GenI 0.17, but
that's a future question to research.Note also that this bug would not have been caught without the
pattern-matching style allowed by languages such as Haskell or one of
the MLs. We simply would have silently accepted the anomalous situation
and the user would have been none the wiser. I consider this a
succesful application of the "Dead Programs Don't Lie" principle.
So yay Haskell!
