Xamarian.Forms Out of memory exception #83

Description

@Leonscape

I'm having a problem with the signature pad on android under forms. After around 35 uses the app crashes with an OOM exception inside android. This was tested on a J3 phone with version 2.1.1 With version 1.5.1 this problem doesn't happen, and I can repeat the calling of the page as many times as I like. I've attached a demo solution that exhibits this problem.
