You are asking for a large allocation which by definition must be
contagious in virtual addresses yet your virtual address space don't
have a free range of such addresses available.
So, I should consider myself lucky to get even my 1.1 GB contiguous
VM, depending on what I have running on my system... If I kill
Safari, with its now 2.68 GB VM, it could possibly succeed? How
about first thing after a reboot? I guess the issue is really that
even with a 64-bit VM address space, there's no guarantee even then
that it would succeed. Maybe some sort of VM recompaction is due in
OS X (Leopard)?
