- Use VM_ALLOC_NOBUSY to eliminate vm_page_wakeup() calls and the
acquisition and release of the global page queues lock required to make
those calls.
- Remove GIANT_REQUIRED from vm_hold_free_pages(). All of its VM operations
are properly synchronized.
- Hold the lock on the containing vm object when calling
vm_page_sleep_if_busy().
- Eliminate unnecessary calls to vm_page_busy().
