[lwip-users] [lwip] The timers in the TCP

[lwip]

Hi , I have a question regarding the timers in the tcp module - the delay ack 
and the rtx.
This is the scenario:
while handling a certion tcp_pcb in the main thread in tcp_output, the 
tcp_timer_coarse
is called and use the unacked and unsent lists of the current handled pcb in 
the main thread.
Is this scenario safe - it seems to me that both threads can use the unacked 
and unsent lists 
of the same pcb?
Thanks
