When you're controlling Tor with something like stem and you need **a**
port, not a **specific** port. Especially if you want to be guaranteed
that you will get a port (what if something is listening on $RANDOM
already?).

For example, Simple Bandwidth Scanner launches Tor for itself and tells
it 'SocksPort auto'. It's conceivable someone wants to control a relay
with a script in a similar manner.
