/*!
|
|
* Linked list of events.
|
|
* Global events are appended to the list by append_event().
|
|
* The usecount is the number of stored pointers to the element,
|
|
* excluding the list pointers. So an element that is only in
|
|
* the list has a usecount of 0, not 1.
|
|
*
|
|
* 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.
