I kind of like TRANSIENT, but that's only because it's a property I've
been working with in some other systems

http://www.erlang.org/doc/design_principles/sup_princ.html

Restart = permanent | transient | temporary

Restart defines when a terminated child process should be restarted.

A permanent child process is always restarted.
A temporary child process is never restarted.
A transient child process is restarted only if it terminates abnormally, i.e. with another exit reason than normal.

What about NOT PERSISTENT ? Then we would have two flavours of them,
that's NOT PERSISTENT ON RESTART TRUNCATE or ON RESTART FLUSH, I guess?
