It isn't messy, it's the correct way to do it. You're not
stripping the process of it's streams, your disconnecting
it from it's controlling TTY, which, if it closes before
the app, sends a DIE! signal to the app; that, or your
app freezes or dies when trying to use it's console.

I suspect someone's yanking someone else's chain; I used to
write perl programs also, and whenever I needed an app to
totally disconnect from it's parent, I *had* to close it's
link to the console, or it's parent's console, which basically
means that I had to redirect std{in,out,err} to /dev/null,
in whatever mode you want.

It's not that nasty, you know.
