I think the original problem was a race, so it is not easy to reproduce.
I ran this patch in a loop over night with some stress plus
the mcelog test suite running in a loop. I cannot guarantee it hit it,
but it should have given it a good beating.

The kernel survived with no messages, although the mcelog test suite
got killed at some point because it couldn't fork anymore. Probably
some unrelated problem.

So the patch is ok for me for .16.
