There is only one way to figure out and it had been described upthread.
For Linux such experiments had been done and results were very clear -
price of TLB flushes was considerable and that's aside of the complexity
of supporting a lot of mappings with partial VM sharing. For Plan 9 the
answer might be different, might be the same, but there's no way to
pull that answer out of thin air. FWIW, I suspect that full-shared
VM would be a win, but it can only be decided by trying and comparing.
End of story, unless somebody has time for that work and is willing to
do it.
