Ugh, is this patch really dependent on such a thing?

TBH, I think the odds of making that work are indistinguishable from zero;
and even if you managed to commit something that did work at the instant
you committed it, the odds that it would stay working in the face of later
system changes are exactly zero.  I would reject this idea out of hand.
