You input callback will be called any time there is data available to
be read from the pipe. So, if you read all data from the pipe in your
input callback, your callback should only be called when new data
arrives.

Also, I think when the other end of the pipe is closed, your
function will be called (with 0 length when you read from
the pipe) until you close your end and remove the input callback.

Hope this helps,
