We still wait for an extra:
 3 * delay_variance + |delta_seq| * packetization_time.
over the expected receival time. The packetization time factor is implicit 
from the fact that we are waiting from the time when a LATER packet was 

I will add a static safety margin, but the earlier formula is not affected by 
the last fix.
