I will always have that, no matter what system I choose. Even if I
require every call to my mixer to be preceeded by a call to
->supported() instead of relying on the casted object, I have serious
races.

I don't care. And this is serious. I really don't care. There is no
solution. Except for doing proper programming in one's application.

At least for the oss/v4l/v4l2 elements, they all emit signals for
open()/close(), so by knowing this (maybe I need to document that), I
can know when my casted mixer-object stops being valid.
