[Spice-devel] why spice server is not aware of client-disconnection.

[David Jaša]

This is because spice relies on default tcp behaviour. IMO the only
alternative is to have some heartbeat in main channel that would
initiate client disconnection if the connection is interrupted.

Spice behaviour is analogous to e.g. IRC behaviour while the latter is
similar to e.g. XMPP/Jabber (or other non-archaic IM) protocols that
detect disconnections almost instantly.
