Are there any problems caused when you are in the middle of typing in
some block of code, so at some points the file will not be complete,
correct tex/latex code, and if tex/latex is run then, you will get
errors (and the previewer may barf)?

(I use latex, but it would seem that you would have a similar problems
with tex.)

Currently, I use (Ed Reingold's) tex-mode in emacs, so while I'm
editing, I have xdvi running, and periodically run latex on the file
from within emacs (xdvi automatically looks at the new .dvi file).

I was thinking of writing some emacs code that automatically runs
latex on the file every so often (perhaps when it auto-saves).  The
above situation seemed like it would cause problems, though (e.g. if
when it runs latex, I am in the middle of entering a block, so I might
not have the appropriate \end or whatever, and latex -- and probably
xdvi -- will barf).
