- Implemented bug/request #53427 - stream_select doesn't preserve the

  keys. This cannot be backported to PHP 5.3 due to a BC break. See
  UPGRADING for more information.

   local filesystems, this allows files to be returned in native filesystem

+- stream_select() now preserves the keys of the passed array, be they numeric or
+  strings. This breaks code that iterated the resulting stream array using a
+  numeric index, but makes easier to identify which of the passed streams are
