Follow-up Comment #49, bug #50837 (project lwip):

OK. From reading the patch, it seems to look better now. 
tcp_in.c not resetting the persist timer any more looks a little odd. But
since we always call tcp_output() for every received ACK, it should be good I
guess.

And with TCP_CHECKSUM_ON_COPY==0, the added code size should be small, too.

Maybe I'd move tcp_split_unsent_seg() and make it static...
