  Log:
  SVN rev 212873 on 2010-09-19 19:42:04Z by alc
  
  Allow a POSIX shared memory object that is opened for read but not for
  write to nonetheless be mapped PROT_WRITE and MAP_PRIVATE, i.e.,
  copy-on-write.
  
  (This is a regression in the new implementation of POSIX shared memory
  objects that is used by HEAD and RELENG_8.  This bug does not exist in
  RELENG_7's user-level, file-based implementation.)
