Changing the mouse pointer icon

Changing the mouse pointer icon

When linuxconf does something that take a while, the mouse pointer should be changed to reflect that linuxconf is working. One solution to this would be that the GUI front-end change the mouse pointer every time it is sending something to linuxconf and it must change it back whenever it receives something. I don't know if it would create some flickers. This does not requires any changes in the protocol.
