Setting up Eclipse for Hadoop Dev

* Create a new Java project from existing source (point to the top-level folder which has src/ folder inside).

* Turn off build-automatically from “Projects” menu.
 
* Right-click build.xml, choose "Run as > Ant build..."; Choose “compile, eclipse-files” targets.
 
* Build once.

"""
Simple python program demonstrating how certain blocking syscalls can be offloaded to a thread-pool and 
then be able to fetch the results from these system calls in a non-blocking way by doing select() on 
a pipe between the main thread and the threads in the pool. 

This is the technique being used by node.js to offer a unified non-blocking Javascript API even for 
things like file I/O which is traditionally done via blocking syscalls. This idea was described by 
Ryan Dahl at JSConfEU 2009.
