Re: panic: tcp_output REXMT

Yes, you're right. Save syn_cache_get(), of course.

Do you think it would help adding a field to the TCPCB remembering who was the 
last one to arm the retransmit timer and outputting that field in the REXMT

Right again. I must have overlooked something when I looked through the code 
last time. At least that explains why it's not panic'ing all the time despite 
the retransmit timer not being correctly disarmed.
