zero filling pages

Probably a FAQ, but OK anyway :)

Whenever I allocate memory with vm_allocate I get a zero filled paged. AFAIK I can't get around this for security reasons, the reason being that another process should not look into another processes memory space, to glean some information.

OK two questions:

Is there really no (reasonable easy) way to get around this ? Zero filling is my bottleneck currently.

I can see the rationale on a multi-user, time sharing system (AKA as the bad old days), but on a single-user machine like Mac OS X I would not deem it important enough. (Mac OS X Server maybe, but Mac OS X Client ?)

Thanks for any comment.

Ciao
Nat!
