Oh, I certainly agree; my point is that for someone who *really* needs
this capability, rather than just "oh that would be nice and clean...",
there is a route available.  Just as audio workstation users take
Fedora Core and transform it into PlanetCCRMA by running adding a bunch of
packages and running a custom Ingo-turbocharged RT kernel.  In both case,
the stuff might make it upstream one day, or might not.

Xen provides an interesting example too.  Over the years there have been
dozens of checkpoint/migrate/restart mechanisms developed at the process
level, and they are complicated beasts.  With Xen, the unit of encapsulation
is the OS instance, and a non-local filesystem and gratuitous ARP are about
all that's required.
