Yes, I understand why such a design can be uselful. What I said is
that I didn't realise how to separate binder/not-a-binder cases.
But after thinking a bit... actually, you can just define 2 function
templates in a straight-forward way:

// simple functor/function case
template<typename T>
CCycleThread(T t)
{
  m_thread.reset(new
boost::thread(boost::bind(&CCycleThread::execute<T>, this, t)));
}

// binder case
template<class R, class F, class L>
CCycleThread(boost::_bi::bind_t<R,F,L> t)
{
  m_thread.reset(new
boost::thread(boost::bind(&CCycleThread::execute<boost::_bi::protected_bind_t<boost::_bi::bind_t<R,F,L>
> >, this, boost::protect(t))));
}
