  SVN rev 205349 on 2010-03-19 22:39:27Z by attilio
  
  MFC 181019, 183474, 191277, and 191626:
  - Move the code for doing out-of-memory grass from vm_pageout_scan()
    into the separate function vm_pageout_oom(). Supply a parameter for
    vm_pageout_oom() describing a reason for the call.
  - Call vm_pageout_oom() from the swp_pager_meta_build() when swap zone
    is exhausted.
  - In both pageout oom handler and vm_daemon, acquire the reference to
    the vmspace of the examined process instead of directly accessing its
    vmspace, that may change. Also, as an optimization, check for P_INEXEC
    flag before examining the process.
