CLOSED CONNECTIONS IN THE BACKLOG

```
If a connection is backlogged but accept() is not called quickly, then
that connection may time out. How should this be handled? Should the
connection be removed from the backlog if it is times out or is closed?
Or should it remain in the backlog with a status indication so that accept()
can fail when it encounters the invalid connection?
Status: Open
Priority: Medium. Important on slow applications that will not accept
connections promptly.
