I'd start by trying a patch that polls a memory location but doesn't modify the location. If that avoids the regression, we can use an alarm to update the memory location after a certain amount of time, without cost.

For now, I guess I'll mark this patch r-, since it's a step toward a design change that's a performance regression.
