[ale] remote x apps crash X11

[Sergio Chaves]

Apparently there is a bug with a remote X session running over SSH.
Quick Google search "ssh -x crash local session" provided +-6K results for 
infinite amount of distributions.

Interesting links to look at:
http://www.x.org/wiki/Development/Documentation/ServerDebugging
and
http://linux.die.net/man/5/sshd_config  (sshd man page (5) ). 
Looking at the TCPKeepAlive config option, it reads: "Specifies whether the 
system should send TCP keepalive messages to the other side. If they are sent, 
death of the connection or crash of one of the machines will be properly 
noticed. However, this means that connections will die if the route is down 
temporarily, and some people find it annoying. On the other hand, if TCP 
keepalives are not sent, sessions may hang indefinitely on the server, leaving 
''ghost'' users and consuming server resources."

Hope that helps :o)
