Returns the number of seconds to delay when making concurrent attempts to connect to multiple servers.
<p>
If set to 0, connection attempts are serialized. An attempt is made to connect to the first server in the list.
The next entry in the list is tried only if the attempt to connect to the current host fails. This might
cause your application to block for unacceptably long time if a host is down. If set to greater than 0,
another connection setup thread is started after this number of delay seconds has passed.
