Comment:
This is the simplest patch of the cache problems suite, and it does not
depend on !#715, so I begin with this one.
I'm a little bit confused by all those tests for None in your patch.
Isn't the first one sufficient?
More specifically, the second test "if S is not None" isn't superfluous ?
And if it is not None, can G be None ? (I guess there is some cython
voodoo involved here)
To answer my own question, I guess it is none if S is not a Parent (as in
your example with 1).
Once you answer me back, I'll post a reviewer patch with some additional
minor corrections.
