BalancerMembers are doubled workers

During my work on PR 38403 (http://issues.apache.org/bugzilla/show_bug.cgi?id=38403) I noticed that
Balancermembers appear twice in the worker list. First they get created by ap_proxy_add_worker
in add_member of mod_proxy.c and afterwards they are "cloned" by ap_proxy_add_worker_to_balancer
also called from add_member.
Can anybody remember the rationale for this?
These worker "twins" share the same reslist, but use different scoreboard slots. This is at least
confusing without comment.

Regards

Rüdiger

I can't totally recall, but I think it was initially setup
that way to allow for some sort of parent-child/master-slave
setup... I need to look over the old emails.
