[lwip-users] ARP layer and Multithreading layer

Hi group,
I the CHANGELOG file, there is a TODO note like this :
  * TODO: the ARP layer is not protected against concurrent access. If
    you run from a multitasking OS, serialize access to ARP (called from
    your network device driver and from a timeout thread.)
I would like to know if someone have an idea about what kind of problem can appears without such protection (others than exception...), and where to place efficient synchronization in the stack...
