Well, you labeled it as "part 1" and so I mentally said, "okay, I'll
take a look at this whenever it's complete."

Ick.  I don't really like that.  It seems to me that we simply don't
support canceling in any sane way once the installation step has begun. 
Even if we are able to cancel cleanly at a point in between unpacking
two packages, that still could leave the system in a horrid state --
missing dependencies, postinstalls not run, etc.  We should disable the
button for the entirety.
