As well as leaking a connid and leaving the connection open,
these calls to free_client() leave the client in the unknown_list
causing check_unknowns_list() to crash when either ptr->data
(ptr being the freed client_p->localClient->tnode) is NULL or
when client_p->localClient is NULL.
Flag the client as an IO error so that we don't try to send it
any data (as this is not a normal plaintext connection).

Links that are 'no-export' are not distributed to the rest of the IRC network (including local peers).
This provides a core primitive for 'anycasting' services (but the actual issue of synchronizing data in
a services package is left to the authors of the services package).
On FreeBSD 4.8, fork(2) doesn't actually behave like fork(2).
Namely, kqueue(2) descriptors are not inherited by the child.
IOW, we can't fork(2) after we get the kqueue(2) descriptor.
So we'll just have to rely on people to actually read the
server log file if they want to understand why their server
is dying during startup.
