[Interest] How to prevent large qml forms from hitting javascript stack size?

Finally, if you really, really want this, you can patch Qt to produce a 
QV4::ArrayObject on the JavaScript heap rather than just bumping the 
stack. Using the JavaScript heap comes with a performance penalty for 
the normal use case, though. If it's behind a switch that enables it 
only for insane amounts of objects, I will accept such a thing, though.
