/* The default value has been changed many times over the years. It
was originally 5 seconds. But that was thought to be a long time
to sit and wait, so it was changed to 2 seconds. That was thought
to be plenty unless the connection was going through some terminal
server or multiplexer or other form of hairy serial connection.
In mid-1996, remote_timeout was moved from remote.c to top.c and
it began being used in other remote-* targets. It appears that the
default was changed to 20 seconds at that time, perhaps because the
Hitachi E7000 ICE didn't always respond in a timely manner.
But if 5 seconds is a long time to sit and wait for retransmissions,
20 seconds is far worse. This demonstrates the difficulty of using
a single variable for all protocol timeouts.
As remote.c is used much more than remote-e7000.c, it was changed
back to 2 seconds in 1999. */
