Lab 4, Exercise 1

Forgive the pedantry; hope this'll be useful for future n00bs.

"Create a process that just prints the first message it receives with IO.write(:stderr, message)" - I misunderstood this to mean we had to set up receive to look specifically on :stderr channel (instead of intention: any message, and report that to :stderr channel.)
"then dies, it should return the pid of the new process." Does solution.ex actually do this part?
