+Today we talked on IRC a little about this. Dick again mentioned that
+MS.NET seems to use one Thread object across appdomains. It seems that
+other properties of the Thread are propogated across appdomains too
+
+using System;
+
+using System.Threading;
+
+using System.Globalization;
+
+
+
+public class X : MarshalByRefObject {
+
+	static void Main () {
+
+		AppDomain d = AppDomain.CreateDomain("d");
+
+		X x = (X) d.CreateInstanceFromAndUnwrap ("t.exe", "X");
+
+		Console.WriteLine (Thread.CurrentThread.CurrentCulture);
+
+		x.Foo ();
+
+		Console.WriteLine (Thread.CurrentThread.CurrentCulture);
+
+	}
+
+   
+
+	void Foo () {
+
+		Console.WriteLine ("I'm in Foo");
+
+		Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
+
+		
+
+	}
+
+}
+
+
+
+In this test case, the culture in the root domain gets changed to the
+invariant culture. Even if we did a hack where we detected changes to
+the CurrentCulture in one Thread object and made the changes on the
+other domains' thread objects, this would not account for changes to
+the fields of CurrentCulture.
+
+From what I can tell, all instance members of Thread apply their
+changes across all appdomains (ie, they are thread-local). An example
+is CurrentCulture. All the static members apply their changes to the
+tread-appdomain (ie, they are thread local, appdomain local). An
+example is GetData.
