This is FOSS, you have the sources. You don't have to ask someone else
or leave it as an unknown.
You should better grep the sources (or use, eg, Eclipse to do searches
across the whole sources) yourself, looking for anywhere the message
enum is used.
You would see that message is only sent in one place,
lws_context_destroy(). And that's after it has tried to close every
live wsi. And that's after setting context->being_destroyed = 1, which
is a sign to not hope for a clean close but just free things and get
If there's some case missing, that is poking you in the eye, it'd be
really nice if you stepped up and debugged what is missing checking
context->being_destroyed, and sent me a patch fixing it, rather than a
question you could easily answer yourself.
