SP_kill - close a client side connection without notifying the daemon.
int SP_kill( mailbox mbox);
SP_kill should be called when the application needs to close a
connection to the Spread daemon, but does not want to notify the daemon
about the close. The most common case of needing this is when a Spread
client application calls the unix function fork() and needs to close
the connection in either the parent or child since the other will
handle the communcation.
Generally the SP_disconnect() function should be used to disconnect
from the daemon as it correctly and expediently notifies the daemon
about the disconnection. If a client calls SP_kill instead of
SP_disconnect when no other process has the client side mbox open
(because of fork) then the network connection to the daemon will be
closed and the daemon will detect the client as disconnected as soon as
the network layer (TCP) registers a closed socket on the daemon side.
Thus it will appear to the daemon as if a true network fault occurred
or the client crashed as opposed to cleanly disconnecting.
The mbox should be for the connection you wish to close the mbox on.
Returns 0 on success or ILLEGAL_SESSION when the session mbox given is
not a valid connection.
