Oh, sure.  But I'd like to leave enough room for further expansion to
"generic process management" (i.e., manage any running process).  In
that case, the "process" would be the most generic process
representation, from which "child" could inherit.  We'd then have a
"current_process" class or something that inherits from "process" too.

Yes, that's what I'm thinking.

Indeed.
