Yup. And the core reason for our headers mess is that the headers do too much stuff, and cnosequently demand a large dependency trail.

Probably mm.h should be split up - put the simple things (usually declarations) into one "early" header file and leave the more heavyweight things (usually implementations) in mm.h.
