CPU usage 100% when no internet connection

PingMenu uses 100% CPU if there is no internet connection. I noticed when watching a film on a plane with my Macbook pro, the fans turned on a the CPU was at maximum, and a very high Energy Impact (see below image). This has been easily reproducible for me, every time I turn on my computer and have not connected to wifi yet.

Actually, it seems this only occurs the first time PingMenu starts, when there is no internet, and is unable to get internet. If PingMenu is already started and has had access to the internet already, then later if there is no internet it will not exhibit the behavior of 100% CPU. In this case, it behaves just as if the ping is not responding. I believe the case when DNS is not available, and PingMenu has not yet cached the IP address of the ping host, its search for DNS is blocking.
