# check_ping results will depend on whether the ping command discovered by 
# ./configure has a timeout option. If it does, then the timeout will
# be set, so check_ping will always get a response. If it doesn't
# then check_ping will timeout. We do 2 tests for check_ping's timeout
#  - 1 second
#  - 15 seconds 
# The latter should be higher than normal ping timeouts, so should always give a packet loss result
