Same as fixed but Overflow will silently drop the messages.

Like fixed but Overflow will cause the buffer to expand dynamically.
New messages will be buffered up to limit. Overflow will raise an Error. Omitting a limit value will result in a limit of 10.

No buffering, new messages will be lost if there are no pending takers
Same as fixed but Overflow will insert the new message at the end and drop the oldest message in the buffer.
