// making everything go through the UI thread, avoiding contention.

|
|
//
|
|
// 4) happens through DisposeNative directly. OnDetach is not
|
|
// called.

|
|
// and only make a pending call if the destroyed flag is not set.
|
|
//
|
|
// 7) is solved by taking a lock whenever mWindow is modified on the

|
// Gecko thread or accessed on the UI thread. That way, we don't

// release mWindow until the UI thread is done using it, thus avoiding
