is there a simple test program which segfaulted before the patch was applied 
and works now?

I am curios what this patch works around and see if we could fix the root of 
the problem.

Andreas?

Summary:  loopif results in NULL reference for incoming TCP packets

Original Submission:  When connecting to "localhost" with the loopif interface, 
tcp_output doesn't get the opportunity to finnish sending the segment before 
tcp_process gets it, resulting in tcp_process referencing pcb->unacked-> which 
still is NULL.

Small fix in loopif to let tcp_output finnish off, before sent to ip_input.
