There are many systems and other services where this is NOT SUPPORTED by the
operating system vendors and DOES NOT WORK.
Don't generalize the FreeBSD/BSDI/OpenBSD/Linux world to the rest of the
planet. It doesn't apply.
Further, you generally CANNOT bind one task (ie: a web server) to more than

given subset). Multiple processes operating off the same data work in SOME,
but not all, cases.
