Another option is to keep this mbind(2) specific and overload flags to be
the preferred nodeid.

mbind(va, len, MPOL_PREFERRED_STRICT, nodemask, max_node, preferred_node);

First of all I do not think you really want to create a new memory
policy for this. Not to mention that PREFERRED_STRICT is kinda weird in
the first place but one could argue that a preference of the first node
to try is not really specific to BIND/PREFERRED_MANY. Overloading flags
is a nogo.
