I think it should be. I agree that the workaround is kinda ugly,
and this is really the only clean solution I see. I don't think
it's so ugly that it takes precedence over trying to bring some of
Robert's LW locking improvements into the SSI area, so this one is
likely not to get into 9.2, in spite of appearing to be a smaller
change. So a TODO entry seems like the right way to deal with it.
