+Summary: ExitThead() causes a crash when it's called from the main thread
+
+If you call ExitThread() when there are no threads - for instance before 
+any threads have been created, this'll crash.
+
+I added a workaround for this, but the main problem still exists.
+
+As an example, try a simple
+
+	static void Main() {
+		throw new Exception ("Whatever");
+	}
+
+This is a critical bug since it makes the exception system almost 
+unusable:
+
+ExitThread() is called from arch_handle_exception() on an uncaught 
+exception - and if you get a SEGV there, it'll call 
+arch_handle_exception() again via the SIGSEGV handler.
+
+This means that you get hundreds of System.NullReferenceException's 
+floating over your termain so you can't read the program's output and the 
+real exception anymore.
