How can that work? when the skel is entered, out_array points to garbage
(or 0, in case the marshaller nulls it beforehand). The skel changes
out_array to point to the return value of __alloc, which is somewhere in
heap. However, this new pointer value never gets back to the skel
marshaller (i.e. the function that called skel_Test_ITest_foo) since
arguments are passed by value and not by reference.

I'm sure I'm missing something obvious here -- but my mind races and I
cannot figure out how this could work.
