Comment(by simonmar):
I think `generic_handler` is only run if a handler is installed. Although
looking at the code that doesn't seem to apply if a handler is installed
and then uninstalled again. That looks like a bug, becuase then
`stg_pending_buf` will fill up.
You'll notice that `rts_ConsoleHandlerDone` is completely bogus (see my
comment). However, we could do something similar at the Haskell level -
look at the way exit is handled in `GHC.TopHandler`. Having the handler
automatically exit the process after running is an interesting idea, but I
wonder if it ought to be under the control of the handler (perhaps by
returning a `Bool`?).
