Sorry my previous reply was eaten by my MUA.

That happens.. especially when MUA becomes hungry :)

The main purpose of the asserts is to catch corruption to the Memory
Regions early so we don't see weird failures later on (c.f. the 3
separate bugs for crashes in slightly different places).

IOW is we are crashing on the asserts in this patch but it's booting
without it we are just getting lucky.

Thank you very much for this summary. Yeah, this confirms my thought,
but I wanted to be sure.  I left it in.
