Details:

I have embedded system that runs simple http server.
Every request(new connection) is served in separated thread and then socket
closes. I have about 30kb heap and it get exhausted after about 5000-7000
requests. Especially this reproduces when there are 3-5 or more simultaneous
requests to the server at once.
This issue is not reproduced when LWIP_TCPIP_CORE_LOCKING_INPUT is 1. So I
think there could be something connected with messages inside the stack since
LWIP_TCPIP_CORE_LOCKING_INPUT changes the execution flow to avoid using
messages.
I use v2.0.RC2
