The first case described (differing number of ports) I'm not 100% sure 
about. I'm thinking the little used slash notation in the SDP m= line 
might be to blame... one side using it (say, 1234/2 to advertise 4 ports 
being used), the other side not using it. You'd end up with 4 ports open 
for each side, but some of them unused. And then UDP packets coming in 
on those ports.

The race condition is harder to test. You'd have to predict which ports 
will be opened when an "offer" is received, and have these ports 
hammered with UDP packets ahead of time, while the "offer" is being 
processed.
