Class Loading Performance Issue

[deviljelly]

Hi,

I'm suffering a production performance issue with BeanShell. I don't control the application or script. The bsh classloading infrastructure does not cache a classforname miss therefore is constantly buzzing through the classpath including hitting the disk and opening zip files. Would it be possible to have a "Production Mode" where misses are cached and saving the billions of cycles per transaction I'm currently paying.

This is related to the discussions at #570 about simplifying the class loading process.

This should be resolved with that PR too.
