Merged
Conversation
There was a slight race condition on shutdown as the watch routines tried to recreate the containers as we were removing them on shutdown. Fixing this by keeping the lifecycle management in the watch container routine itself.

Seems ok, it's a little confusing with the global context in addition to the per function contexts in Stop / Borrow but I don't really understand this bit enough to offer more constructive feedback, so LGTM

Should m.ctx.Done() be checked as well or is that implicit in the wait group / done?

Actually the manager's ctx will always be done here, since we call m.stop() in the beginning
