I don't deny it's a bug fix; I'm just dubious about the risk-reward
ratio.  As to risk: the patch isn't trivial (notice Alvaro didn't get it
right the first time).  As to reward: it's been like that since forever,
so if the problem were really serious, we'd have identified it before.

Letting it age a bit during beta would do a lot to damp down the risk
side of the equation.
