The only place I can think of that it might hurt is if someone has squirreled
away tm structures in a disk file. If that's happened, the committee's
desire to avoid breaking existing code would argue against changing the tm
Now if you change the structure's name, then code will break noisily--
something the committee seems willing to accept.
