Sometimes there is a need to remove pending messages of an object. For example,
when the main purpose of a thread is to carry out work asynchronously using
invoke messages, then there might be a need to stop processing because some
kind of state has changed. This can be done in two main ways: flushing messages
or removing them. This changes enables the second option, which is useful if
the effects of the pending messages are no longer desired.
