It's fixed on mainline and I'll probably backport the patch to 4.0.1. 
As I said at the time I committed the mainline patch, it was too
invasive to commit right before 4.0.0 was released.

It's been on mainline for a couple of weeks now, and I don't think it's
shown up any problems, so now is probably the right time to be
back-porting it.
