Describe the Feature Request
A large table dumping on thread 3, while threads 1,2,4 have finished, makes it appear as mydumper is frozen

** Message: 20:24:23.267: InnoDB tables completed
** Message: 20:24:23.268: Waiting threads to complete

** Message: 20:24:24.131: Thread 4: shutting down

In the above, it states "InnoDB tables completed", but that's not 100% true. Threads 1, 2, and 3 are still dumping large tables. But you can't really see that unless you scroll back/troll through logs.

Expected output
Perhaps after each thread has finished, the status of remaining threads is re-outputted so users can see more clearly that other things are still happening.
