+1.19 Timeout idle connections from the pool
+
+ libcurl currently keeps connections in its connection pool for an indefinite
+ period of time, until it eithe rgets reused, gets noticed that it has been
+ closed by the server or gets pruned to make room for a new connection.
+
+ To reduce overhead (especially for when we add monitoring of the connections
+ in the pool), we should introduce a timeout so that connections that have
+ been idle for N seconds get closed.
