At least they should not be used from multiple threads. The lwIP core 
should only be used by the tcpip thread. Application (socket-using) 
threads communicate with the tcpip thread using mailboxes.

None that I know of: I'm using one normal netif plus the loopback netif 
without problems. Even using 2 netifs (using the win32 port) is no problem.

Wow, that's really old!!! I'd strongly suggest you to think again about 
that: there have been _numerous_ changes and bugfixes since 2003 (that 
must have been lwIP v0.6.0 or older?). I'm afraid you won't get too much 
support for such an old version here... :-(
