I have load-applet (0.8.2-2). But I use it from many months (and many
tablets and OS versions) and I never had any problem...

I know... my use case for the load-applet is that I use it to
understand when a click on Google Reader was understood by the
tablet... I see the CPU gauge going up for some seconds... ;-) The
same holds true for many Web 2.0 apps... :-)

I have also gnotifier, configured and working. Update time 15 minutes...

of messages I see in system log are "normal"? It doesn't seem so...
