As far as I know, the infinite loop construct is the way to do it. However, you can have multiple processes, each waiting on a sensor, each running in an infinite loop, each using the defer() function to allow switching between processes when appropriate. Some processes can use the msleep() function to effectively lower their priority. This seems to be a fairly efficient way to go.
