If a socket option and an address option is given then the listener will listen on both the specific IP address and the Unix socket.
#### `persistpoolmax`
The `persistpoolmax` parameter defaults to zero but can be set to an integer value for a back end server.
If it is non zero, then when a DCB connected to a back end server is discarded by the
system, it will be held in a pool for reuse, remaining connected to the back end server.
If the number of DCBs in the pool has reached the value given by `persistpoolmax` then
any further DCB that is discarded will not be retained, but disconnected and discarded.
#### `persistmaxtime`
The `persistmaxtime` parameter defaults to zero but can be set to an integer value
indicating a number of seconds. A DCB placed in the persistent pool for a server will
only be reused if the elapsed time since it joined the pool is less than the given
value. Otherwise, the DCB will be discarded and the connection closed.
