Log Message:
-----------
Fix race in TCP Main <> TCP Worker communication
As a TCP worker has 2 comm channels (one TCP worker specific and one worker
generic) to TCP Main, be sure we have a consistent communication (over the 2
channels) between the TCP worker and TCP main.
The actual fixed race: the TCP workers creates a new TCP conn (and sends this
event as TCP worker to Main) and when trying to write to the conn it fails (and
sends back a bad-conn event to Main, but as generic worker) - the 2 events are
delivered via different comm channels, so their order may be lost, reasulting
to bogus behavior
(cherry picked from commit bfb62212ea4b4895b3174653b11d33e7ecb92751)
