"""
 This class is the application that launches checks
 The poller listens to the Arbiter for the configuration sent through
 the given port as first argument.
 The configuration sent by the arbiter specifies from which schedulers the
 poller will take its checks.
 When the poller is already launched and has its own conf, it keeps on
 listening the arbiter (one a timeout)
 In case the arbiter has a new conf to send, the poller forget its old
 schedulers (and the associated checks) and take the new ones instead.
