What's the status of fixing memory leaks in Xamarin forms

Hi I see some issues about memory leaks like Bug 25404 - Navigation Page Leaks Memory (https://bugzilla.xamarin.com/show_bug.cgi?id=25404) and I found this happening with very simple navigation page and even with the Xamarin Forms samples.
It really stops us from continuing with Xamarin Forms if it can't be fixed quickly.
Can you give us any insight of the status?
Thanks
