##Die, with the possibility of reincarnation##
Sometimes you want to create a “kill loop” which is just an infinite loop that terminates the execution of your program. However on the Spark Core this will cause your Core to not process the background tasks that allow it to talk to the Cloud, and also allow it to be reflashed OTA (Over The Air). To create a kill loop, that allows you to reprogram your core, you can just infinitely call the background tasks directly with code like this. Here we detect a failure connecting to our temperature sensor, and die… with the possibility of reincarnation 
if (!bmp.begin()) {
Serial.println("Could not find a valid BMP085 sensor, check wiring!");
while(1) Spark.process(); // Die, with the possibility of reincarnation
}
