That would be possible, but frankly if we're going to include
a more portable alternative, I'd prefer to include _just_ the
more portable version, and accept any performance penalties (or
whatever) on platforms where mprotect would have worked.

The reason for this (and also the reason I haven't jumped at
the non-mprotect alternatives) is that _all_ versions contain 
icky portability and/or correctness issues, and I don't want
to have to maintain more than one.
