It doesn't cause any obvious problem, but I couldn't reproduce the
original slowdown so I'm not sure whether this patch fixes it.

In any case, I won't push it yet since I won't be able to commit
followups timely in case it breaks something — but if someone else wants
to push it before I get back, feel free.

Cheers,

Daniel
