from man mlock:

mlock() locks pages in the address range starting at addr and
continuing for len  bytes. All  pages that contain a part of the
specified address range are guaranteed to be resi‐ dent in RAM when the
call returns successfully; the pages are guaranteed to stay in  RAM
until later unlocked.

so reading every page seams unnessesary to me.
