It just sends SIGINFO, and there's a default handler that does something
which is normally useful. dd installs a custom handler that is more
useful.
Sure; what I'm wondering is if there's some way to show some basic AFS
stats in the default handler.
I don't believe so. It looks like there's a lot of tty magic involved,
and I am not seeing any hooks that kernel modules (or even just
filesystems in general) could use.
http://fxr.watson.org/fxr/source/kern/tty_info.c#L214 is what seems to be
producing the default behavior.
