title: Is passing of data with one signal to multiple slots safe in Qt?
body: <p>My Qt application is continuously receiving data packets from server side and on basis of data, it is constructing object.
  I have to pass these objects(one at a time) to three different widgets. So, I have connected one signal to slots of all three widgets but I doubt if it is safe to pass objects like that? Suppose the data packets arrive at fast rate, will these get overwritten with new data packet? Can the objects get corrupted due to this or can I loose some packets or data while I am processing the older packet.</p>
  
  <p>Is there a mechanism to ensure that overrun does not happen. Also, will there be some throttling if the data packets at a very fast rate.</p>
