Does LwIP make any asumption on the
order that semaphores are released.
I.e. if two threads use LwIP does the
LwIP TCP/IP-thread assume that the messages
sent over a common message box will
be received by the threads in the order that they are sent?
Or is it ok to have a "polling"
semaphore system where threads waiting on the same semaphore might
be woken regardless to how long they
have been waiting.
