Is there an error message each time the cache is unable to write the
package cache?  Do permissions not allow you to write to the cachedir?
Are you referring to PyServlet or some tool that uses sys.add_extdir?

You can limit the jars in your classpath to limit the startup overhead.
This is also good because extraneous jars seems to have a performance
effect on Java loading anyway (or is it just me?).

It would be better to get the cache to work property as it seems an
important optimization.  Make sure permissions allow writing the cachedir
and maybe double check to see if the python.home property is correct.
