I do not see anyone passing non-zero in as the flags argument.

It is difficult for me to determine the impact of this patch,
whether it should really go to 'net' and/or 'stable', etc.
if you don't tell me who this could possibly break.

It's even worse when I do all of the searching around and
cannot find a breakage case myself. :-/
