  Modified:    sys/vm    vm_extern.h vm_fault.c vm_map.c vm_map.h vm_mmap.c
  Log:
  Implement closer-to POSIX mlock semantics.  The major difference is
  that we do allow mlock to span unallocated regions (of course, not
  mlocking them.)  We also allow mlocking of RO regions (which the old
  code couldn't.)  The restriction there is that once a RO region is
  wired (mlocked), it cannot be debugged (or EVER written to.)
  
  Under normal usage, the new mlock code will be a significant improvement
  over our old stuff.
