I am totally stumped.  I have no idea how what you have in mind.

The mbind, set_mempolicy and get_mempolicy system calls plainly and
simply apply only to the current task, and it would take changes in
kernel code and the system call API to change that fact in any
sensible way.

You've dropped one hint: its a quite significant change.

If you have the patience, could you drop a couple more hints on how
to do this (make this change by just changing libnuma)?  Perhaps with
a little more technical meat on their bones?
