I met Bert the other day and he explained this sorcery to me as well :-) There is one case in which apparently it can also work, but also in >= Vista systems: a given LSP might just be a wrapper (used by firewalls / malware protection stuff), so there seems to be some API which is used to ask the provider "are you a wrapper?, what's under the hood?", so chances of success are much higher. FWIW, I used to expose this in pyuv (a property which was true if the handle had that 'slow' flag) and I could never get it to take the slow path. Cheers, -- Saúl Ibarra Corretgé bettercallsaghul.com
