I'd restrict that to say that the convention is to do this if your app
is meant to be executed from a shell or shell script. When you're
writing code meant to plug into another application, all bets are off.

Particularly with Qmail as Antonio was looking to do - Qmail has some
very weird conventions and most of the different pieces talk to each
other via different set of predefined file descriptors and you don't
really have any choice.
