Should not be in waiting as it is analysised and confirmed as a bug on the mainline 
already and the waiting use is only for waiting for response from the submitter and this is 
waiting from a developer.

I think we should just close this PR.  In comment #9 Andrew suggests that this
should be a pessimizes-code, but there is no test case for that and no reason to
think that we do pessimize the code.  If there is some problem with the
implementation of an array of restrict qualified elements, I think we should put
that in a new PR with a test case.
