threading/Manager: Switch inf bucket from infinity() to max()

Browse source 
For uint64_t, std::numeric_limits<T>::has_infinity is false and infinity()
actually returns 0. Use uint64_t's max() instead. We could cast to double
and use the double infinity, but this seems reasonable, too.

This was found while trying to provoke some pending messages and being
confused why all but the "inf" bucket increased.
