Fixes a regression in 1453f7b013393678b8a616d7cfbda1b68b2c31db

Fixes a regression in 1453f7b013393678b8a616d7cfbda1b68b2c31db that causes unnecessary wait_timeouts in certain module operations when a given IP address could not be found.  Now wait_timeouts are only active during address associations of newly provisioned EIPs.

Cleanup and comment of main().
