Probably this is because I did not comment that sufficiently: Those
simple_recv_ functions are really meant as a short-cut if there is
nothing but this single call in the _recv function. If you have to do
anything but this call, do it manually. That was at least my intention
when I wrote this function. Sorry if this is not clear enough.
