I make heavy use of supervision in all my applications. While it's
been said that more than a couple levels of supervision becomes
unwieldy I insist on every process being supervised. If for no other
reason than that application:stop/1 should cleanly stop every process,
or in a more practical sense `q().` from a shell prompt should exit
silently and without hanging.
My LAPD protocol implementation(*) uses three levels of supervision
and is well documented:
The fun comes in when you are dynamically starting and stopping
processes in the tree.
