Review comment:
Addressed by not acquiring the lock for *internal* `MailboxProcessor` mails.
I.e., `allActionsCompleted()` and 3 other similar actions don't use
`MailboxExecutor` and `StreamTaskActionExecutor` and go directly into `Mailbox`.
Please see hotfix commit 63d104b52a7fbca8a4d2dd2ce0f4a8d4bdad8178.
