The test case waits for master_pos_wait not to timeout, which
means that the deadlock between SQL and IO threads was 
succesfully and automatically dealt with.
      
However, very rarely, master_pos_wait reports a timeout. This
happens because the time set for master_pos_wait to wait was
too small (6 seconds). On slow test env this could be a 
problem.
      
We fix this by setting the timeout inline with the one used
in sync_slave_with_master (300 seconds). In addition we 
refactored the test case and refined some comments.
