Tracebacks are even more expensive than I thought. If you look at PyTraceback.java, you can see that PyTraceback#getLine does not even attempt to cache the line, or optimize access to the file by getting multiple lines. So this means we should at least port Lib/linecache.py to Java to speed things up (https://docs.python.org/2/library/linecache.html), as well as avoid a dependency in Python code for something as critical as the traceback.
