In his case, what was largely the problem was that his Perl was
misconfigured and was trying to parse through a GREAT many more Perl
libraries than was needed.  Each invokation of resend took about 5
_minutes_.  Believe me, I helped track down and fix the IS possible to do that.  It is much HARDER to do
something like that (misconfigure in such a way) under C.

You are, however, correct that sendmail did not aid the situation.

I will also admit I am biased against writing applications in scripting
languages as a general rule, because I've seen some things done very, very
wrong in them.  I've seen some things done wrong in C as well, and I've
seen some things done right in scripting languages, but as a general rule
for some reason I feel more like daemons and such should be written in C
or C++ or SOMETHING that compiles and produces a binary.

When I see things on freshmeat like 'HTTP Daemon written in Perl' or 'MTA
written in Perl' or 'FTP client written in shell scripting language', I
just want to run screaming and hide under my desk. :)

Good song. :)
