Just a quick update.
I've been analysing and profile the behaviour of my new dict and messing
about with various implementation options.
I've settled on a new implementation.
Its the same basic idea, but with better locality of reference for
unshared keys.

For those instances which keep the default, yes.
Otherwise the answer is, as Martin pointed out,
it could yes provided that adding a new key does not force a resize.
Although it is a bit arbitrary when a resize occurs.
The new version will incorporate this behaviour.
Expect version 2 soon.
Cheers,
Mark.
