Since Ted asked about older platforms where memory is an issue, well the
kind of "container" technology in Linux certainly isn't "lightweight" --
there's a ton of extra code in the kernel to make it work.  (CGroups)

I _think_ FreeBSD Jails are less heavy-weight but it does get its
tendrils deep into quite a wide variety of kernel subsystems.

Both incur a huge amount of code complexity to the kernel.
