#
# Reports the load time (in milliseconds) of URLs from url_list 
#   as a metric named "pageloadtimes.<hostname>" to librato. 
#
# For easy instrumentation, the URL is reported as the metric's "source" 
#
# If a http response code <> 200 is encountered, it will report 9999
# as a magical way to indicate failure.
