Sorry to drag this up again ...
I have done a little more testing and simply adding -i 100 allows fping
to succeed on my buildbots. (more or less, some pings fail but target
is alive)
Also note; over 60 pings (my tests) this adds about one second,
so for 20 pings (t_client) this will add ~300ms per fping test.
These timings are very approximate because using -c 20 -p 250 -i 50
ran faster than -c 20 -p 250 -i 25 by ~300ms, see last tests attached.
