ruby - rubystate_machineの状態間の中間遷移をトリガーする

Question

https://github.com/pluginaweek/state_machineを使用しています

私のコードは

event :set_running do
 transition any => :runnning
end

event :restart do
 transition :failed => :restarting
end

after_transition :failed => :restarting do |job,transition|
  job.set_running
end

after_transition :restarting => :running do |job,transition|
  job.restart_servers 
=begin 
 this takes some time. and i would like job state to be "restarting" while
 it's restarting servers. but it doesn't happen (i suppose because of transaction) 
 until after_transition :failed => :restarting callback is finished.
 so it actually doesnt happen at all because this callback triggers => :running transition
=end
end

つまり、「restart」イベントを1回実行し、：failedから：runningへの転送中に中間遷移をトリガーしたいと思います。どういうわけかstate_machineを使用してそれを行うことができますか？
