OK. I see, diff doesn't show complete entry. The thread entry function is named
tmain. Here it is:

    // Create a main thread, so we can run the scheduler and have time 'pass'
    cyg_thread_create(10,                       // Priority
                      tmain,                    // entry
                      0,                        // entry parameter
                      "socket echo test",       // Name
                      &stack[0],                // Stack
                      TMAIN_STACK_SIZE,         // Size
                      &thread_handle,           // Handle
                      &thread_data              // Thread data structure
            );
    cyg_thread_resume(thread_handle);           // Start it

And tmain() doesn't do any echoing, it merely inits lwIP and starts thread
"main" - entry point net_test(). "main" performs echoing and that's why I
thought you were refering to MAIN_STACK_SIZE.
Anyway, now I see that I was not fully consistent. Maybe I should put
TEST_STACK_SIZE instead of MAIN_STACK_SIZE. Then we shall have:

  TEST_STACK_SIZE
  LOAD_STACK_SIZE
  IDLE_STACK_SIZE
  TMAIN_STACK_SIZE

What do you mean?
