It's a revert of c1afdaff90538ef085b756454f12b29575411214, so so just
take a look at the code in c1afdaff90538ef085b756454f12b29575411214^.

The fact that the patch as not been applied/reviewed/accepted upstream.

Personally I don't see what is the problem with reverts; we already
know the previous code was working. Sure, in theory it might behave
different due to other changes, but that doesn't seem to be the case
here, plus, it can't be worst than the current situation of staying in
an endless loop.

It appears in 3.4 there are more issues, so the fix there might look
completely different, but regardless, the real issue is that the
proper fix is not yet here.

So the question is do we want 3.3.2 to be completely broken for these
machines, or not?
