 Summary: TextReader.Read from System.Console.In is incorrectly blocking
@@ -61,6 +61,34 @@
 It doesn't look like a "traditional" blocking/non-blocking issue.
 MS "blocks" indefinitively but returns after the first new line.
 Mono doesn't consider the new line (probably because it use a
 FileStream) so it returns only when the buffer is full.
+------- Additional Comments From sebastien at ximian.com  2006-01-02 11:22 -------
+I added tests (r54954) for StreamReader and StringReader and their
+Read methods don't return when they encounter a new line. So this
+seems to be a console-only feature.
+Another similar test case (because a new line is 2 characters under
+using System;
+class M {
+	static void Main ()
+	{ 
+		char[] charbuf = new char[10];
+		int nRead = Console.In.Read(charbuf,0,10);
+		Console.WriteLine("1Read = {0}\n",nRead);
+		nRead = Console.In.Read(charbuf,0,10);
+		Console.WriteLine("2Read = {0}\n",nRead);
+	}
+Type: "123456789" then Enter
+and you'll get
+so we must keep the NL logic between calls to Read.
