OK, I think the light bulb over my head is beginning to make buzzing noises and glow dimly.

We have not tried this yet (and please correct me if I am wrong), but it appears that the user watchdog is set to timeout after .1 seconds, and since our user code is sleeping for .5 seconds, nobody is kicking the dog, and it is therefore zapping us.

First, this evening we are going to try just disabling the user watchdog during init to see if that corrects the issue(?) Based on the results of that test, we will investigate changing the structure of our code to put some kind of dog-kicking mechanism into a separate thread, or setting the timeout on the watchdog to 1 second, or leave it disabled. (If leaving it disabled is verboten, PLEASE let me know!)

Assuming we are now merrily on our way, thanks for the input!
