I did also want to make another point about this.  Processors are not
getting that much faster; it's not 2001 anymore.  We've pretty much
hit the wall for single-core performance, and compilation is an
extremely difficult problem to parallelize.  Yes, you can compile
multiple files at once, but if a single compilation unit takes 20
minutes to compile, it doesn't matter how many cores you've got.  The
shortest compile time you can get is 20 minutes.  Even if your
compiles are "only" three minutes, if you spend three minutes
compiling, followed by ten minutes of testing, that means you're
spending almost a quarter of your time compiling.  That doesn't seem
like an efficient use of time.
