  24 #This class is an interface for the Receiver
  25 #The receiver listens to the Arbiter for the configuration sent through
  26 #the port given as first argument.
  27 #The configuration sent by the arbiter specifies on which schedulers
  28 #the receiver will take broks.
  29 #When the receiver is already launched and has its own conf, it still
  30 #listens to arbiter (one a timeout)
  31 #In case the arbiter has a new conf to send, the receiver forget his old
  32 #schedulers (and their associated broks) and take the new ones instead.
