#Note, this pping still frontends fping. I think it would be possible to write a perl equivalent, but
#I've not had the time. Net::Ping shows perl code I could see being adapted for a somewhat
#asynchronous ICMP ping (the tcp syn is interesting, but far too limited, and that is currently the only async
#method Net::Ping provides.
