Clients have a pointer to the last event processed, and for each of these clients we track the usecount of the elements. If we have a pointer to an entry in the list, it is safe to navigate it forward because elements will not be deleted, but only appended. The worst that can happen is seeing the pointer still NULL.
When the usecount of an element drops to 0, and the element is the first in the list, we can remove it. Removal is done within the main thread, which is woken up for the purpose.
For simplicity of implementation, we make sure the list is never empty.
