True.  Just so I understand, was the point of the original commit (which has now been reverted) to run tcpip_callbacks on the calling thread for the core locking case?

​Yes. I thought this would be a perfomance gain​
​ - no context switch needed any more​
​ in the good case.​

I do wonder if the current system (using the TCP/IP thread for callbacks) would be better for an SMP system where another thread could complete the callback in parallel once the thread posting the callback releases the core lock.
yes, correct, that case would be faster.​
