[IRCServices] what do they think ?

     This requires the overhead of spawning a new process for every
request, which can lead to a denial of resources attack on the whole
system if someone really tries, as opposed to a DoS on Services alone.
(You could get around this by imposing a process limit.)  It also relies
on the fact that the machine running Services has a sendmail that works
the way you expect--this is not a given, believe it or not.

     "Works" and "works under all conditions" aren't quite the same thing.
If your code works for you, fine; but for a program designed to work
across many different environments such as Services, "works" just isn't
enough.
