it's not, neither Plan 9 nor Unix support this in a general way. There are
systems that support this in a limited way, however.
People keep wanting migration across OS instances to work the way that it
works on CPUs in an SMP. It doesn't, and never has, except in very special
cases. It's easy to get the easy parts right, hard to get the hard parts
right, and impossible to get the impossible parts right. Most people stop
at easy and call it a day.
