Replying to [comment:11 simonmar]:
> It also varies based on `tablesNextToCode` and other things, but you
only need the upper bound here. I would add an `stgRetInfoTableMaxWords
:: Int` somewhere, maybe `CmmInfo`.
That would be handy though I have no idea how to generate such a constant.
Do you intend to hardcode it?

I found it was my misunderstanding while I was trying to explain why it
was wrong to calculate `nearLimit` by the number of tables. Sorry, you
were right.
