Subject Re: WP8 memory leak
Date Tue, 17 Jun 2014 17:49:52 GMT
The memory leak was caused by event listeners for PhoneApplicationService.
I unwired them in CordovaBrowser_Unloaded (pull request:
https://github.com/apache/cordova-wp8/pull/41). It fixes the leak but I
want to make sure it doesn't go against the intended behavior.
