Yeah, if you do a full shutdown, I would definitely wait a little
for the old process to shut down (wait for pid to disappear), first.
However, full shutdown means you drop connections, so I would use
USR2 followed by QUIT (on same pid, USR2 will replace the current
pid file). See http://unicorn.bogomips.org/SIGNALS.html

Yeah, skip the before_fork and also after_fork. Those are mainly for
disconnect/reconnect of ActiveRecord and anything else that might need a
network connection.
I try to have as little-as-possible in my unicorn config.
