This idea is related to Tom Tromey's incremental compiler work
(http://gcc.gnu.org/wiki/IncrementalCompiler) and to Per Bothner's
compiler server work
(http://per.bothner.com/papers/GccSummit03-slides/index.html).  Neither
project is currently active.  I believe that Diego Novillo is currently
doing some work along these lines but I don't know what the status is.
