It's the wall-clock time for the user that's important. OK, some of us
are lucky and work on fast machines: millions of potential users out
there are on dumb terminals on overloaded VAXen, old 386s, Goddess knows

Coming from the other end of the spectrum, real-time formatting is not
that hard either. After all, if you want robust fast formatting, you can
always lift the core code from TeX and use that, shorn of its batch
environment and syntactic dependencies; some systems already have.

I take back what I said about modifying the DTD not being permitted, I
didn't understand fully what was being implied.
