Bill,
I think the main issue is that noone is really using the event API, or am I
wrong there? In my years active with lwIP, I haven't seen a single mail on one
of the lists mentioning the event mode...
It does save some code space and execution time in the stack, but at the
downside of code portability: you have to combine *all* TCP communication into
one function, which is really not optimal to me...

That's a good question.

Because these have nothing to do which each other? I do use NO_SYS but I would
never use the even API, I guess (for reason mentioned above).
