FWIW, we use the before_fork hook to automatically kill the old master
by sending it QUIT:
before_fork do |server, worker|
old_pid = '/var/www/api/shared/pids/unicorn.pid.oldbin'
if File.exists?(old_pid) && server.pid != old_pid
begin
Process.kill("QUIT", File.read(old_pid).to_i)
rescue Errno::ENOENT, Errno::ESRCH
# another newly forked workers has already killed it
end
end
end
