I'd be grateful if you would cite the issue. I don't have the full history of 
lwip-devel in my inbox :-)

As to your original question, the original implementation of timeouts using 
sys_arch_timeouts was somewhat buggy as it could lead to re-entering functions 
that were not reentrant. It has been removed completely with 1.4.0.

Instead, stack-internal timers are handled by the stack itself. Support for 
timeouts in application threads was dropped, you have to implement these 
yourself if you need them.
