These can either be set to an integer, in which case it's interpreted
as a TCP port, or a string, in which case it's treated as a unix domain
socket. If the unix domain socket is prefixed with a "@", it will be
treated as an abstract socket.
When stored in the ini file, there is always a prefix added to make
parsing the string more systematic and less ambiguous. A port number is
prefixed with "#", an abstract socket with "@", and a socket file with
the prefix "P" for "path".
