        As for whether breaking connections after a fixed number of tries is
a good idea, I don't believe it is. It's no harder to write a program to try 1000
passwords on one connection than it is to write one to try one password,
disconnect, and repeat. So how would that provide any protection against
brute force attacks?

It doesn't, although it does increase the amount of time it takes for
the brute force attack to be successful, which can be a deterring factor
when you have, say, a slower network link and are forced to
connect/disconnect for every password attempt.
