	I'm not interested in saving RAM no :-) I am particularly interested in
a bug-free and debuggable panel.

	+ 99.9% of Gnome users use the panel
	+ 1% of users use JimBobHackedLeetShLibApplet which corrupts
	  memory badly, uses global variables, can't cope with multiple
	  instances etc.
	+ 1% of users file "it crashes" type bugs with confusing 
	  back-traces on the panel - regularly.

	Thus we get screwed by people doing stupid things beyond our control.

	If you're applet is useful enough to be in the core distribution, it's
likely to be used enough and read enough to be sufficiently bug free
that it's worth making it a shlib component.

	Otherwise it's a really bad idea for everyone IMHO.

	How are you measuring memory usage. Looking at memory usage I get (for

	Total 6.6Mb
	RSS   6.3Mb
	Share 5.4Mb

	So - yes, it seems that in real terms it consumes ~1Mb to run the
battstat applet. It would be interesting to see how that breaks down. [
the size goes up having used a dialog eg. ].

	I have various suspicious and prejudices, but run memprof on it and do
a module breakdown somehow, and we'll see.

	I'm suspicious of (in no particular order):

		gtkrc state
		GObject property strings
		i18n string tables

	do post a breakdown though, and we can look at the speed/size tradeoff
again with some good new data.
