There is nothing new about Jython 2.0 that makes it any more or less
a compiler.  There has always been a compiler that compiles Python
source code to Java bytecodes and a Python runtime invoked by the
compiled code.  There was indeed a lot of work done to get Jython 2.0
released, but there was no fundamental change to the architecture.
