In addition to. What I meant by "instead" was to replace
your proposal of --with-segsize-mb.

Well, it's a developer/debug focused API. I think regular users
would only care for the existing --with-segsize = so-many-GB API.
But for testing, I think --with-segsize-pages = so-many-pages
is actually a pretty good UI.
