| Start Watching

| the watcher will poll for changes every second. You can adjust this by
| passing in an optional first parameter. The interval is given in
| microseconds. 1,000,000 microseconds is 1 second.
|
| By default the watch will continue until such time that it's aborted from
| the terminal. To set a timeout pass in the number of microseconds before
| the watch will abort as the second parameter.
