__instadapt__ happens only when you define an __adapt__ on the Interface, which
is *also* deprecated up the wazoo. So I'm not sure there's much point in fixing
this.

Sometimes, when you adapt an object to an interface, t.p.components checks if
__instadapt__ is a member of the interface. This calls __getattr__ somehow,
which raises a DeprecationWarning.

I'd patch, but I'm not sure whether we want to ignore then entire __getattr__
apparatus, or just the warning.
