Personally, I *always* read these names backwards - from the POV of
the caller. So when I see "add_send_fifo", I then expect to be able to
send stuff on the returned FIFO (i.e., I get a writer back). But
that's not how it works.

I may be alone in this - I've had similar problems in the past with
how people name pipes, for example - but I thought I'd raise it while
there's still a possibility that it's not just me and the names can be
changed.
