It is a linked list now; the server allocates memory for each interface
present on startup.
The code could be changed to use the poll() if someone really needed
more interfaces, as I'm pretty sure that select() is the limiting factor
now. Well, outside of any OS limitations on number of supported
interfaces (I assume we are talking about virtual interfaces or perhaps
aliases, and not actual hardware).
