"Is an error" (which the standard uses) and "behavior is unspecified"
(which is used by the C/C++ standards, and maybe we should switch to it
in R8RS) mean the same thing: the implementation can do what it likes,
and the user cannot rely on the results.
So what's meant is that the user can't rely on the contents of the queues
passed to this procedure.
