settimeofday().

7dfeb8e7ce create demand-paging mapping in case of MAP_SHARED
On current McKernel, only mappings for demand paging can be shared.
Therefore, if MAP_SHARED and MAP_ANONYMOUS are specified and
anon_on_demand is disabled, then mmap(2) should create a mapping which
is for demand paging and is entirely populated with physical pages.
