yes

i have made my own BSD socket layer for lwIP (connect(), accept()
etc.) and compiled a single threaded web server for it. I use
my own operating system: PaulOS.

I loaded the web server all night with thousands of hits - far
more than it can handle. It worked perfectly, neatly dropping
connections.

Note that I have done some bug fixes to lwIP that I had submitted
to James, but I havn't checked if they have been included. You
generally have to use a memory allocation tracer to see that
everything is in order. I also substitute all lwIP allocation
with my own.

I also use a memory monitor that disallows connections
when the resources are low. In this way there is no chance
that resources will run out.
