I think you underestimate the problem. "line noise" in sendmail
is a compact way of writing complicated regular expressions.
In zmailer it is less compact, but there are still regexps.
Put them in S-expressions if you want, but the overall effect will
be similar if you solve the same problem.

No, you get that message because those sites really do want to limit
the amount of network traffic they have to put up with. The unix
kernel does a much better job of multiprocessing than any user-mode
solution will be able to. Why complexify your ftp daemon when the
current arrangement is so simple and elegant: one process per
connection.
Needless to say, in either case a one megabyte scheme
runtime system makes this idea a non-starter, especially for
sites who are limiting network connections due to performance
concerns!
