Description

Since the 3.7.0 update, when cordova does a Js to Native call using exec(), somehow the underlying cordova.js is creating a "gap://ready" iframe on every call. This means that if you made 1000 native calls you'll have 1000 divs on the DOM.
I believe this issue is of critical priority as it incurs a huge memory leak.
