Generic interrupt command?

Hi all,

I think a cool addition to runit program sv and s6's s6-svc would be a
command to send an arbitrary signal to the daemon being supervised.
Let's say a -z was added as an arg to s6-svc or a "genericinterrupt" was
added as an arg to sv. Now you could say:

sv genericinterrupt SIGIO myspecialdaemon

s6-svc -z SIGIO myspecialdaemon

The supervisor already knows the PID of what's being supervised, so it
would be an easy way to get an arbitrary signal into a daemon, for
those daemons that have non-standard signal usage.
