An excellent suggestion.

One last question: how exactly do you suggest to achieve that on my Jolla?

(Actually, my main PC up to September 2013 had 1GB RAM and no swap and it never ran out of memory, despite habitually running some quite heavy applications. Just the antivirus alone took about 30%. That a mobile phone with the same amount of RAM cannot manage even three running apps is a scandal that screams "incompetence" loudly and clearly for the whole world to hear.)
