  Modified files:
    lib/libc/stdlib      malloc.c 
  Log:
  Fix a race condition in arena_ralloc() for shrinking in-place large
  reallocation, when junk filling is enabled.  Junk filling must occur
  prior to shrinking, since any deallocated trailing pages are immediately
  available for use by other threads.
