Note that tcgetsid(3) is part of posix 2008... I don't see this as a noxious interface, so I don't see any reason not to keep it... In ports, devel/ddd uses it as a fallback on systems without setsid. lang/sbcl checks for it, but it definitely is just wanting to create a wrapper for it. (apparently, vala has similar code, just looking thru google). Oh, hey, and it's in Stevens... so we MUST have it :)
