The JSR-223 API provides Writer/ErrorWriter/Reader properties for the 
engine to use for stdio.

Attached is a quickie patch that gets output working.  I didn't spend a 
lot of time figuring out exactly how it should be implemented for this 
particular code, but it does work with IFCX Wings.

I didn't include the ReaderInputStream adapter for supporting input 
because I don't know if the license is OK for Jython.  It is Apache, and 
I used it in the IFCX version of the Jython engine.

In addition to scripting.dev.java.net, you can also see it in IFCX.org
