We have something like that for when applying one of the erratum fixups that is sensitive to 4 KiB page boundaries, this can involve rounding up the size of the thunk section. It could be possible to switch something like that on after a number of passes that would likely prevent the slow creep of additional thunks.

Thanks for the suggestion!
