I guess the user will want to choose between MAP_SHARED and MAP_PRIVATE.
This can be added in the future.
Good idea, it will allow guest to write data but discards its content
after it exits. Will implement O_RDONLY + MAP_PRIVATE in the near future.
FWIW, if Igor's backend/frontend idea is implemented, the choice between
MAP_SHARED and MAP_PRIVATE should belong in the backend.
Yes. I can not agree with you more! :)
