It's not necessary, but I think it's easier to not make a special case
of main(); the rules for creating well-written code are easier to
remember if they don't have more special cases than they have to.

Also, there's always the possibility that code from main() may someday
get moved off to another function; if that code already contains
properly connected malloc() and free() calls, that's one less thing to
worry about during the move.
