There have been projects to do this at various times on linux.  Having
a namespace dedicated to a certain kind of application is no big deal.
Someone would need to care enough to test and implement it though.

The latter I need to check on.

The pid namespace is well defined and no a task will not be able
to change it's pid namespace while running.  That is nasty.

We have had that discussion mostly this appears to be a measure of
