mainline in general heads for the straight and
complete virtualization approach, they do not bother
with performant isolation and corner cases (yet)

nah, not _that_ much heavier, but, in certain cases
too heavy compared to what Linux-VServer is doing.
for example, consider 1000 guests with a single
daemon running inside, on mainline that would give
2000 processes (init + daemon) while we can do with
only 1001 processes (single shared init)

yes, and we are providing this in _addition_ to
the process isolation, as alternative ... so the
choice (which one you prefer) is yours
