If you wan't your new updates to take effect you'll need to restart every 
application/daemon that uses a library affected by the update. Rebooting 
quickly becomes the easiest way to make sure of that.

It kind of depends on what you wan't. If you're ok with the fact that maybe 
some of the updates won't take full effect until the next reboot then fine.
