Removed the warnings, instead have a sync.Map where they are registered/unregistered and can be inspected with an undocumented monitor page. Added the notion of "in progress" which is the number of messages that have beend pop()'ed. When recycle() is invoked this count goes down. Signed-off-by: Ivan Kozlovic <ivan@synadia.com>
