Well, if your other patch to make it OK to be on-stack would be applied
instead, this wouldn't make much sense either :)

In this particular patch, we could reduce the size of the struct, but I
don't actually think it'll make a difference to go from 48 to 36 bytes,
given alignment etc., so I think I'll just leave it as is.
