Instead of installing the files in /usr/lib/node/libraries and loading them from the file system, the files are built-in to the node executable. However, they are only compiled on demand. The reasoning is: 1. Allow for more complex internal javascript. In particular, process.stdout and process.stdin can be js implemented streams. 2. Ease system installs. Loading from disk each time is unnecessary overhead. Note that there is no "system" path for modules anymore. Only $HOME/.node_libraries.
