I don't know what is reasonable. A KDE desktop with just KMail open 
requiring 2GB of ram seems not reasonable to me, but maybe showing the 
contents of a folder with 30K mail can not be done without using 1GB of ram.

I'd hope mysql can be tuned to not eat 300-500 MB ram and if virtuoso can be 
folded into that, it'd save a fair bit. Still, it all seems a lot. 
Thunderbird and Evolution use nowhere near those numbers...
