Could we also speed up the following cases:

1) sock->rcvevent already > 0
2) sock->sendevent already 1

I’ve noticed case #2 from debugging when receiving ACKs from a full window of 
data, each ACK calls sent_tcp, which calls event_callback() and iterates the 
list.  This seems unnecessary since any waiters would only be waiting for the 
transition from buffer full to open.
