I don't think you need a separate refcount field. Also it's not called
"basefilter" in other quartz components. In fact you don't use it at all
it seems in patch 6/7, and I think 7/7 is short enough to merge it with 6/7.

I think this is usually FIXME or WARN.

Style-wise, I think naming could be improved, for example "impl" part
does not add anything.
