If anything that would just exacerbate the problem. All of the SWIG
utility functions would be repeated for each module. In any case, I
split the file into 2 and the total time for compiling both is about
the same as as compiling the current sparsetools_wrap.cxx. This would
be a win for parallel builds, but until numscons is the official build
system, I'm against making changes as invasive as splitting up an
extension module just to optimize for that.
