  24 #This class is an application that launches actions like
  25 #notifications or event handlers
  26 #The reactionner listens to the Arbiter for the configuration sent through
  27 #the port given as first argument.
  28 #The configuration sent by the arbiter specifies on which schedulers the
  29 #will take actions.
  30 #When the reactionner is already launched and has its own conf, it still
  31 #listens to arbiter (one a timeout)
  32 #In case the arbiter has a new conf to send, the reactionner forget his old
  33 #schedulers (and the actions that goes with them) and take the new ones
  34 #instead.
