I would have expected the function s0_0 to be destroyed upon client disconnect.

Message:
So, I can assume you fixed it like that? Or did you mean that this bug is
invalid?

Message:
The quit() command can be embedded in MAL functions, easily leading into a
shooting in the foot when you clean out the user module. However, we can
clean it upon first re-use of the client context.
