Socket broken in dart bleeding_edge?

socketTest.dart

#import('dart:io');

main() {
	Socket s = new Socket("127.0.0.1", 8888);
	print('s = ${s.available()}');
}

/*

From the folllowing build socketTest.dart had no problems running. 
http://gsdview.appspot.com/dart-editor-archive-continuous/5549/dart-editor-macosx.cocoa.x86_64.zip
$> /tmp/dart/dart-sdk/bin/dart socketTest.dart 
s = 0

On dart-sdk from Version 0.1.0.201203232000, Build 5803, Dart SDK version 5803, Dartium version the following error happens
