A few places, but not many.  Although it depends on your definition of JVM 
being the limiting factor -- the fact that the JVM can't run CPython module 
written in C removes a lot of useful libraries.  There is some 
functionality of file objects, and the sys, and os modules in particular 
that is just not offered by the JVM.

There are other CPython/Jython differences, of course, but those are the 
main ones stemming from limitations of the JVM itself, rather than 
differing design decisions.

Hope this helps,

Noel
