So I pull the entire tree, make some changes, do a build.  I want to
sync with the latest changes in my component (whatever it is), but
have to pull everything.  To save build time, I build just my
component.  But then my built bits no longer correspond to my source
tree.  Debugging becomes a new challenge.

That's the best case, when I'm on the corporate network, close to the
server.  Over my dsl line at home, it takes 24 minutes for everything,
vs. 1 min 10 secs for hotspot (the only part I need).
