I think we are using the same words to mean different things.

I was using this from the point of view of writing a gdb extension using
the new feature.  E.g., consider the log-printf code.  The new method is
used by log-printf to do its work.  Here, the method is an
implementation detail of log-printf.

I'm sorry for being unclear.

I don't really agree, but I think it is less important than getting some
variant of the patch in.

Phil is already implementing this and I think should have a new patch
shortly.
