Fix select_proxy dead loop in round_roubin_chain 

Fix issue #147.
If all proxies are in DOWN_STATE or BUSY_STATE state, select_proxy will run
forever in an infinite loop. When all proxies are not available, we wait some
intervals and retry. The wait time starts with 10 milliseconds and is
increased by 10 milliiseconds in each loop. 14 loops sums up with 1.05 second.
