Are you *sure* that doing this is necessary?
Reserving address space in this manner seems a pretty odd thing to do,
and my inclination would be to look carefully at what you're doing
that is making it necessary to use all these ".zerofill"s, since your
program is probably better off without them.
Might be worth posting some questions to darwin-dev explaining what
the problem is, if you haven't already.
Kind regards,
Alastair.
