I am having a hard time imagening use cases for such a feature since I
usally see special code sections optimized to run without OS jitter and
not whole processes. AFAICT You would not want to have any of these on
because they cause performance regression if you must do syscalls related
to process startup and termination.

Since we are adding docs: Could we have some sample use cases for
when these features are useful?
