[Interest] Memory consumption when starting QML application

[Shantanu Tushar]

Hi,

Using a Loader in this case is the ideal solution. Our application also has
multiple "screens" that we load lazily. Some of them are loaded only when
the user navigates to them, and some of them are loaded after a slight
delay.
