It's worth pointing out that this is an exceptionally fragile area of
the code thanks to some regrettable historical decisions with regard to
how GPIOs are managed so this assessment is based on repeated past
experiences with changes that look sensible, fix real problems for real
systems and yet cause problems to crop up elsewhere due to unforseen
interactions elsewhere. Eventually we'll shake out all these issues and
end up with something that's more understandable and hence managable but
clearly we aren't there yet.
