I wasn't sure what to do this with interface; we could have a set of interfaces
for each; or remove this entirely? Up to you.

I think this (InProcessWorkerObjectProxy) is not useful/necessary. +1 to remove
this.

Sounds good. I sent out a separate patch for this removal+rename, and made this
change dependent.
