Put that way, I have to wonder if the right thing to do is just to have
a "try_huge_pages=on|off" setting, and log a warning if the attempt did
not succeed. It would be easier to document, and I don't think there's
much point in making it an error if the allocation fails.

P.S. I'd be happy to do the followup work for this patch (updating
documentation, etc.), but it'll have to wait until I recover from
this !#$&@! stomach bug.
