Startup with rubygems can be pretty slow. Of course, once your app is 
running it should be fine; you can turn on profiling later in the code.

Sounds reasonable - I'd expect /usr/lib/ruby/gems/1.8/gems/*/lib

Not sure why so many directories there; you'd have to analyse that list 
yourself.

Clearly, something is requiring them. But I'm not a Windows user, so I 
can't help you pin this down further. But since highline is something to 
do with terminal interaction, I'd certainly expect it to try to load 
termios, and perhaps Win32API on a Windows box.
