From: Aline Manera <alinefm(a)br.ibm.com&gt; When updating the system, the user should be able to see the progress to know what is being done in the system. stdout.read() will wait until get the completed output to return, ie, the user will see the progress only when the update finishs. So use stdout.readline() to read line by line and display the info to the user.

From: Aline Manera <alinefm(a)br.ibm.com&gt; When an error occurs during an update the user should know the error to report or solve it. So properly update the progress area with task information when an update fails.
