I suspect that the author of that article may have not been aware of the 
caching, so numbers going up might not be a bad thing: Another article 
described how Safari memory usage dropped from 200M to 40M when Firefox 
was opened - which I interpret as "when some other application needed 
the memory".

In other words: It might be that Gecko limits its caching to a 
configured memory "roof" while WebKit rely on the OS to limits its 
playground, but is quick to then drop cached parts when needed.

Seems complex to measure properly.
