# The playing_delay and buffering_delay give three values
# (min, max, offeset) in seconds.
#
# The min tells how long before the cancel policy is allowed
# to kick in. We can not expect to receive a piece instantly,
# so we have to wait this time before having a download speed
# estimation.
#
# The max tells how long before we cancel the request. The
# request may also be canceled because the chunk will not be
# completed given the current download speed.
#
# The offset gives a grace period that is taken into account
# when choosing to cancel a request. For instance, when the
# peer download speed is to low to receive the chunk within 10
# seconds, a grace offset of 15 would ensure that the chunk is
# NOT canceled (usefull while buffering)
