Basically Python applications are usually not too CPU-intensive; there
are some ways you can get parallelism with reasonable extra effort;
and for most of Python's history, multi-CPU systems have been rather
exotic so the GIL didn't create too big a problem.  Right now it is
starting to become more of a problem than before, but it's not yet
intolerable.  Obviously something will have to be done about it in the
long run, maybe with PyPy.
