I'm pretty sure this is possible. There is a function for linking
processes.

Links are bi-directional in Erlang. From this Lambda the Ultimate post
on Termiate, a Scheme distributed framework:

http://lambda-the-ultimate.org/node/view/841

"Termite links are unidirectional but Erlang links are bidirectional.
There seems to be consensus in Erlang-land that it would be better to
have unidirectional links, though you still need to make sure that
bidirectional link-pairs can be created "atomically" enough (maybe
easy)."

Multiple linked processes are allowed. For example a parent that spawns
5 worker processes. All worker processes need to know if the parent dies
so they can die gracefully.
