+Summary: Hang when exception is thrown from static constructor
+
+The runtime hangs when an exception is thrown from a static constructor.
+Try this:
+
+using System;
+
+public class Test
+{
+	public static void Main ()
+	{
+		try 
+		{
+			Broken.DoSomething ();
+		}
+		catch
+		{
+		}
+	}
+}
+
+public class Broken
+{
+	static Broken ()
+	{
+		throw new Exception ("Ugh!");
+	}
+	
+	public static void DoSomething ()
+	{
+	}
+}
+
+The method is executed, but the execution never ends.
+The problems is that the exception is raised from inside a domain lock, and
+this lock it is never released.
+
+I'm attaching a proposed patch. It is not the best patch in the world, but
+I can't find any easier solution.
