A little off-topic, but the sprintf() approach is because MPI chose to
use character strings as a portable format for hints. Very different set
of constraints than us, makes a lot of sense in that set of constraints.

makes sense. Making the caller sprintf into a string to create them
doesn't (even if that's what's mpich does :-)).
