[Pianod] web client how to?

[Perette Barella]

The <defunct> processes get cleaned up on the connection.  I saw something about avoiding zombies entirely, I think by setting SIG_IGN on SIGCHLD.  I'll check into that.

For 'address already in use', could this mean there's no IP6 ports configured on the machine?

Running on port 80.  Ports below ~2000ish are reserved well-known ports, and in shared hosting environments this restriction keeps riff-raff like us from putting naughty things there, like fake services that collected passwords.  It should run there if you start it as root/invoke it with sudo.

If there's a man page for arc4random on Linux, can you mail me a copy?  Maybe that'll say how to get rid of the implicit definition warning.  If not, maybe I'll update the Makefile to use the old random on Linux.

On the client... There should be 'Stations' and a couple other buttons on the bottom to switch panes.

I've gotten that message in other contexts too; is it because the port number has a different standard service?  Or firewall thing?
