Extensive test cases often lead to a lot of log output,
which at times tripped the following assert:

The pass bits of the oc's flags wasn't cleared before or'ing the new
pass on failing the busy object test in the ban lurker. This would
cause the pass not to be matched later, making the lurker spin on the
busy object.
