A competent programmer like our ppc maintainer could likely do
an AIX port in under a week, we just don't have access to the hardware
and nobody offered it or the money to push us to do the port.

There is nothing fundamental in mono that depends on NULL dereferencing
(in fact our jit already has the IR needed to represent a null check,
so a non-optimized fix for AIX stupidly making the 0 page readable is in
the order of 20-30 lines of code).
