Solve the following python programming problem given the following code:
def test_get_events_includes_ofport(self) : 
    utils.wait_until_true ((lambda : self.monitor.has_updates)) 
    self.monitor.get_events () 
    br = self.useFixture (net_helpers.OVSBridgeFixture ()) 
    p1 = self.useFixture (net_helpers.OVSPortFixture (br.bridge)) 
    def p1_event_has_ofport() : 
        if (not self.monitor.has_updates) : 
            return 
for e in self.monitor.new_events ['added'] : 
            if ((e ['name'] == p1.port.name) and (e ['ofport'] != ovs_lib.UNASSIGNED_OFPORT)) : 
                return True 
utils.wait_until_true (<MASK>) 
    
    Given the code above, what is a proper replacement for <MASK>?
