--- Comment #6 from torvald at gcc dot gnu.org --- We can keep it open, but my guess is that it would need some volunteer to actively drive the backporting process. I.e., with a patch and testing. Given that TM is experimental, I think backporting fixes for TM has low priority on most people's todo list.
