Subclasses which mix in L{_SendmsgMixin} must define this. @ivar _sendmsgQueue: A C{list} of C{int} holding file descriptors which are currently buffered before being sent. @ivar _fileDescriptorBufferSize: An C{int} giving the maximum number of file descriptors to accept and queue for sending before pausing the registered producer, if there is one.
