	As you say, we should use setValues to improve the roundtrip efficiency
there lots; more importantly we should use getValues.

	Ok; so - it depends what interface you want to expose really; do you
want to expose one that can be inconsistant ? ultimately even the
setValues results in a slew of separate setProp's - (unless you
sub-class PropertyBag and grab that method). [ albeit without an idle
loop happening between them ;-].

	It's still being maintained; but I'm not sure how we could make this
better for you. You might like to consider some of the properties being
structs - that's no problem, that batch together values that must be set
atomically; I'd love a patch that made setv/getv use set/getValues
though :-)
