Re: [lwip-users] LWIP Process Model confusion:

I don't think the core would have to free anything in the case of the  
threaded code. If you are a one machine system, don't actually copy  
the data in the mbox_post: Ignore the size.

If you are a multiprocess machine, you have to allocate the space in  
the sys_mbox_post code on the other client machine (or process), and  
it might be a little tricky. The sender's (or poster) side should be  
easy. I have to think about the recv/fetch side.
