What happens to other clients listening to the data ? This sort of configuration option would again be along the lines of a systemwide change prompted by needs of one subsystem but affecting all others - something Andrew had recommended against doing while we were discussing the per-tgid turnoff.
The existing way to solve this is for the listeners to close the socket and reopen again later when they are interested. If there are no listeners at all, data won't be sent by the kernel anyway. Won't that work for you ?
