Note: this could be lower for 32bit, but I would still need to be larger than
512KB, which would mean that 64bit would be larger than 1MB if calculated based
on kPointerSize, so I have just set it to be the same as the existing 64bit
limit.  Let me know if you would prefer it set differently.

I guess it is fine, I do not have a strong opinion there.
