Hi Ludo,

Thanks for your detailed comments, most of which I agree with, and I
will make the required changes. There is one issue I see:

> How about (1) calling it =E2=80=98cached-channel-instance=E2=80=99 (or si=
milar), and (2)
> not opening a connection to the daemon?
>
> Regarding (2), it means that procedure would be a monadic procedure and
> it=E2=80=99s up to the user to do with-store + run-with-store or whatever=
.  The

That would imply that the user always opens a daemon, even if it is not
necessary because the required instance is already in the cache. Is that
a price worth paying for a more conventional interface, in your opinion?

Cheers,
  Konrad.
