+to process WebRequest.cctor() under mono on OSX:
+
+using System.Net;
+using System.Threading;
+
+class Test {
+  public static void Main(String[] args)
+  {
+//    WebRequest.Create("http://www.google.com/");
+//    Console.WriteLine("WebReqeust.Create End.");
+    Thread t = new Thread(delegate(Object o) {
+      WebRequest webRequest = WebRequest.Create("http://www.google.com/");
+      Console.WriteLine("Thread: WebReqeust.Create End.");
+    });
+    t.Start();
+    t.Join();
+  }
+}

+stack trace ---
+
+The exception above does not happen when the commented code is enabled
+(i.e. when no async call to WebRequest.cctor() happens).
+
+It seems to happen only on mac.
+
+Filed under class lib (System.dll), but is also likely the runtime issue.
