    sys/vm               vm_map.c vm_map.h vm_pageout.c
  Log:
  - When the VM daemon is out of swap space and looking for a
    process to kill, don't block on a map lock while holding the
    process lock.  Instead, skip processes whose map locks are held
    and find something else to kill.
  - Add vm_map_trylock_read() to support the above.
