I know - I chose the mail title mostly for fun. Nevertheless gen_server
as it is now is not suitable for transient gen_servers where the
init() cb may return an error.
If this is your usecase it is better to roll your own server - which
is boring.

This patch can be made completely backwards compat and should be
added in some form.
