This has been mentioned a few times, I'm surprised it's not mentioned in the
FAQ (Victor or Paul?). With a 1 Ghz machine, you'll probably have to run
"SlowDown.exe" one or twice to let NCU keeps up with the serial data
pipeline. Available on UNNA <http://www.unna.org/>.

brain dump n.: [common] The act of telling someone everything one knows
about a particular topic or project. Typically used when someone is going to
let a new party maintain a piece of code. Conceptually analogous to an
operating system core dump in that it saves a lot of useful state before an
exit. "You'll have to give me a brain dump on FOOBAR before you start your
new job at HackerCorp." See core dump (sense 4). At Sun, this is also known
as `TOI' (transfer of information).
