No, and your point is an essential point that many miss. And I think it
bears a brief focus (and if you are reading this, the moderator agreed).
Even Eric Allman (father of Sendmail), cannot understand a program with 10s
of thousands of lines of C code. It is way too complex. But we could look
at 10 lines and come up with a high level of assurance that a server like
this is bug free and safe. We can do it less easily with 100 lines, or even
1000 lines.* Though our level of assurance might be less, it is still
possible. We -- no one, is what I mean -- could never do that with 80,000
lines of code.

and ask Rick or Marcus for help. :-)]
