The biggest improvement isn't the compile time, it's the fact that the
memory working set for g++ when compiling the previous
gnuradio_swig_python.cc file was 650 MB.  This would cause massive swap
thrashing on machines with say, 512 MB of RAM, or less, and drive the
compilation time up to potentially hours.

This is great! I have a fairly new machine with 1G ram and a dual core
AMD cpu, and compiling GNU Radio used to bring the computer to its
knees :), so this is a great improvement. It is also good news as I
intend to run GNU Radio on my EKIFA single board computer, which only
has 128MB of RAM.
