Using thread variables you could do:

def initialize
	@thread = Thread.current
end

def doSomething()
	@thread[:state] = 'doSomething'
end

def doSomethingElse()
	@thread[:state] = 'doSomethingElse'
end

def start
  initialize()
  doSomething()
  doSomethingElse()  <-- Three hours into processing
  doMore()
  cleanup()
end
