I second Ben's request. There usage scenarios that call for re-init lwIP or even just shut it down. Currently that is not possible because there is no way to exit from tcpip_thread.

Currently, lwip does not offer cleanup functionality, so once it is initialized, it must remain initialized until the process terminates.  This helps keep lwip lightweight and simple, and works well in embedded environments that start lwip at boot, but it does not always work well for other use cases, such as libraries that offer functionality backed by lwip.

Those use cases would seem to be better served if lwip offered sufficient API to clean up all initialized state, and later re-initialize if needed.
