Remarks
Remove any pending posts of Runnable <var>r</var> with Object <var>token</var> that are in the message queue. If <var>token</var> is null, all callbacks will be removed.
This operation is worst case O(n) in the number of messages in the queue, and should be avoided. Instead consider another mechanism outside of the queue to cancel a pending operation. For instance, maintain a flag to indicate whether the operation should be performed differently or not at all once it is dispatched.
