I flashed your watchdog code to the spark.
Your code in the CCP ran fine.
I uploaded my Xivley Code from Sparks online IDE because it would not compile in Netbeans. It looks like the watchdog is not running because its not fixing the network error messages.
So here is the code I'm trying to run with the Watchdog code. If I have to load everything via Netbeans then how do I get it to compile in Netbeans? Fun stuff!

, you explicitly activated the watchdog and you explicitly (involuntarily maybe) flashed some code blocking your 
Lots of things we could log as diagnostics here, and show examples in user code how to interpret these logs and take action. These logs should probably only be cleared through an exposed function, to make it more difficult to lose information.
May be those should be picked up by the Spark team for a consolidated milestone, may be they’ll just get discarded
