An API for scalable I/O operations on both files and sockets, in the
form of either asynchronous requests or polling.  This API will make it
possible to write production-quality web and application servers that scale
well to thousands of open connections and can easily take advantage of
multiple processors.

This API is being developed under the Java Community Process as part of JSR-051.

Done? So how do I do select in java? Please email me.

So how do I get the JSR-051?

JSR-051: see
http://java.sun.com/aboutJava/communityprocess/jsr/jsr_051_ioapis.html

Public release of an implementation seems likely to be in
JDK 1.4 (aka Merlin), maybe sometime this autumn?

Search the web for more vague guesses and misinformation;
keywords: java.nio, jdk 1.4, merlin, tiger.

As far as I can tell this isn't fixed.  They've just 
decided that they are going to fix it eventually.

Asynchronous (socket) I/O is included in the java.nio 
package in the 1.4 beta. It actually works (even if there 
are some issues to iron out.)

> scalable I/O ... files ... asynchronous ...

Not scalable DOWN.  Of course we didn't mean THAT.

jsr-51-comments at jcp.org assures me we shouldn't read 
jsr/detail/051.jsp as a promise of console i/o that works.

Vote at bugs/4071281.html if you care.  Be sure to notice 
even System.err is broke if you use System.in to read lines 
in.

"JSR-051" here means
http://jcp.org/jsr/detail/051.jsp

(I hear the less concise link mentioned has been working 
for a longer time, but isn't as concise and can't easily be 
munged to visit, say, jsr 065 re concise object array 
literals instead.)
