mach-o: why is code placed towards the end of a page?

The linker always places code on a power-of-2 boundary towards the end of the page. Is there a reason for this?

Can the code be placed at the beginning of the page instead?

0x1fc8 below is 8136, exactly 4040 if you subtract the __PAGEZERO that goes before it.

	Thanks, Joel
