This commit adds a thread that periodically removes expired connections. The expiration time of a connection can be expressed by: expiration = now + timeout For each possible 'timeout' value (there aren't many) we keep a list. When the expiration is updated, we move the connection to the back of the corresponding 'timeout' list. This ways, the list is always ordered by 'expiration'. When the cleanup thread iterates through the lists for expired connections, it can stop at the first non expired connection.
