I wonder if the comment above ("This method doesn't actually perform any meaningful I/O, and therefore is sync-only.") is still completely accurate, and whether at some point we should consider having a CleanupAsync...

Yeah, certainly. But given that close_notify is just a 60 byte packet, we can probably still consider it as not being meaningful (at least for now).

Yeah, agree it's unlikely to be an actual problem anywhere... But maybe we should do a proper async variant at some point.

Updated the documentation for the method and opened #6012 to track changing the method to be completely async.
