The behaviour with not_unify/2 has now changed (no 
explicit fix was apparently done; so this might be
a side-effect of some other changes):

The previous problem now behaves correctly:

[eclipse 3]: X = 1.1__1.2, not_unify(X,X).

No (0.00s cpu)

*BUT* not_unify(1.0__1.1,1.0__1.1) now fails incorrectly:

[eclipse 1]: not_unify(1.0__1.1,1.0__1.1).

No (0.00s cpu)

and:

[eclipse 4]: X = 1.1__1.2, Y = 1.1__1.2, X = Y.

X = 1.1__1.2
Y = 1.1__1.2
Yes (0.00s cpu)
