It does happen. SSH is not as forgiving to network glitches as one
would wish sometimes. A firewall that drops idle or long-running
TCP connections, a DSL link doing its daily PPPoE disconnect at an
inopportune moment, a VPN tunnel dropping, a hole in UMTS coverage,
have all killed a SSH connection for me one time or another.
