> This looks fine to me.  Is there any case we now fail, such as 'm_maxDeadCapacity == 0' and 'm_deadSize < 0' that might now get through and cause a problem?

I don't see any case we now can fail.
m_deadSize is unsigned, so it can't be < 0.
When m_maxDeadCapacity == 0, we need to prune resources only when m_deadSize > 0, so there condition 'm_deadSize <= m_maxDeadCapacity' is enough.
