It is a bit scary when you realize what it's doing - but hey you'll learn to live with it. ;-> Now, if you want to override something in a program you can't link against (ala the Linux LD_PRELOAD trick), you'll have to wait for Tiger to be able to do that. -Brian

If you have control over the application, a much better solution is mach_override.

Actually, that is a good idea. I wasn't aware of this... All we really need to do is to call a function from deallocate_pages() with the address and the size. I suppose we would still need to force a flat namespace.

If I can't figure anything else out, I may try this. Testing a totally new way of doing this will not be fun though :(

Thanks a lot for the pointer!
