Just to make sure that I am not confused, what you wrote below
matches what I received from you two message upthread.

I am assuming that it is intended that the two messages from you
have the same patch, and the assignment of ALLOC_ARRAY to wargs was
a bug Torsten introduced only to his tree when cutting and pasting.

With that assumption, will queue this one (or the original one,
which to me is the same thing).

Thanks.
