OL> Hmm.. then what happens when you have a circular dependency ? For

OL> C->A ('->' means connected).
So, I've been cooking up changes to the patch and a test for this
case. However, it seems like it's not valid, unless I'm missing
something. The man page for connect() says:
If the socket sockfd is of type SOCK_DGRAM then serv_addr is the
address to which datagrams are sent by default, and the only address
from which datagrams are received.
So, even though you can connect() a DGRAM socket and then sendto()
datagrams to a different location, it doesn't appear that the
relationship between A and B is really valid, at least the connection
between A and B is not functional. In fact, in my testing, if you try
to connect() C back to A, you get "Operation not permitted" because A
is already connected elsewhere.
Thoughts?
