[lwip-users] socket changes and lightweight protection

[David Haas]

I have been meaning to integrate the select() code into the source tree, 
but last week I was very busy on a different project :-( .

If it is OK with everybody, I will work on integrating all these socket 
changes and hope to have it done in a day or two. I will do some 
(limited) testing before I check it in.

Also, I had put in some lightweight protection into pbuf and memp code 
(in a patch) which disabled interrupts. Several people commented on this 
and thought that we should not be disabling interrupts. I agree that on 
many systems this is undesirable. So how about a sys_arch_protect() and 
sys_arch_unprotect(). This can then be implemented differently on 
different systems.

Any comments???

David.
