If a thread is doing only reads, or is only touching
non-Scanned memory, it continues.
How long do threads usually go without touching the stack?
The stack would have to be COW.
When you fork a process, all of its pages are COW. What you
propose is much more complicated. You would either first need to
fork(), then somehow remap certain pages as shared. The remapping
would have to happen in the parent process. I don't know whether
there are even interfaces to do this.
