There will need to be additional changes below here otherwise
connectionswill be modified in the ship thread which is not allowed.But that's really still not enough to get it 100% correct if the intent is to make the default executor of the stream to be what we want -- the stream should be using a per-stream strand instead of the thread's executor. The problem is that
fc::create_listenerdoesn't give access to the variant ofasync_accept()that allows creating the new socket with a different default executor than the listening socket. This is a real shortcoming and without refactoringfc::create_listenerI'm not sure off hand how to fix that.There was a problem hiding this comment.

In this case there is only one SHiP thread and its implicit strand. I agree that it would be better if
fc::create_listenertook a strand.There was a problem hiding this comment.

Yeah for 1.0.x that's fine but we should really get it right on main -- the code is currently structured with the assumption that increasing ship threads 'just works'

Seems passing a strand works.
