Note that this of course is not "safe from element removal" in
general; it is just safe when you remove any element other than the
next element, whereas TAILQ_FOREACH is safe when you remove any
element other than the current one. For example it would not be
safe to call a callback that could potentially remove arbitrary
It may be clearer in this case just to expand the macro in the code
so that it is more obvious what assumptions can be made.
