Dashboard slowness resolution.

It appears that the dashboard uses tcp sockets and quite regularly. With a
misconfigured firewall this can cause serious slow downs in Abiword as the input
is filtered by the kernel. Iptables rules which look like the following are
doing the damage:

iptables -P INPUT DROP

If the administrator or user does not remember to enable INPUT on the loopback
interface after such a rule. Therefore, enabling INPUT on the loopback
interface such as like:

iptables -A INPUT -i lo -p all -j ACCEPT

will resolve this issue. As will removing the dashboard.

Here's the question though: Why does the dashboard use TCP sockets instead of
UNIX sockets? Using UNIX sockets would resolve this issue even with a misguided
firewall configuration.
