I did. It allows me to achieve something I can't now. Steps you provide

arbitrary point and from that point on all newly mapped memory areas will
be unlocked. Don't you see it is different?

What about mlockall(MCL_CURRENT); mmap(...); mlockall(MCL_FUTURE);?
Or toggle MCL_FUTURE if a mlockall call can stop it?
