The tablesync patch enabled even worker to start another worker.
So the above assumption is not valid for now.

This issue seems to cause the corner case where the launcher picks up
the same worker slot that previously-started worker has already picked
up to start another worker.


I'm not sure if what I am seeing is related to this or another issue.

If I create a subscription for a publication that doesn't exist (yet) I see 'publication mypub does not exist" in the subscribers log

If I then create the publication on the publisher the error doesn't go away, the worker process keeps spinning with the same error.

If I then drop the subscription and recreate it it works.
