Make idle loop not miss a chance to schedule

Prevents the case where McKernel misses one chance to schedule a

add shared mapped file (in progress)
...
implemented:
- Pages can be shared between maps.
- A change made to a map is written to the file, at munmap().
not yet implemented:
- VM operation during page IO execution.
Because page IO is executed with VM's lock.
- Page IO, which does not change a file size with any case.
When munmap() races with truncate(), the file size may be changed
illegally.
