How much overhead would it be to buffer all the way to the end of
a file, and write out before proceeding to compilation proper?
When a segfault occurs, things are going to be pretty scrambled,
you'll want your tokens safe on disk.
Or you could have -save-temps read ahead by a half-million tokens
or so, then dump before proceeding into compilation proper. You
can prevent bloat (although -save-temps is something you use when
you're desperate to debug and not caring much about size/speed),
but still most .i files will be complete and well-formed.
