i'm not sure about jitter, but for the offset calculation as long as at
least one packet is recieved things are okay.  it sends 4 requests and
*tries* to read 4 replies, but if plugin_timeout/2 passes first it will
stop and work with what it's recieved.  so if the "best match" only
responds with 2 packets, then the average will be calculated from that.
