+TargetMilestone: ---
+Summary: WaitHandle.WaitAll() for multiple handle for STA thread
+Seems like WaitHandle.WaitAll() for multiple handle for STA thread is
+prohibited on .NET. Mono simply allows it.
+using System;
+using System.Threading;
+public class Test
+        [STAThread]
+        public static void Main ()
+        {
+                AutoResetEvent ae = new AutoResetEvent (true);
+                AutoResetEvent ae2 = new AutoResetEvent (true);
+                WaitHandle.WaitAll (new WaitHandle [] {ae, ae2}, 1000, true);
+        }
+Actual Results:
+no error.
+Expected Results:
+$ ./sta-waitall.exe
+Unhandled Exception: System.NotSupportedException: WaitAll for multiple
+handles on an STA thread is not supported.
+   at System.Threading.WaitHandle.WaitMultiple(WaitHandle[] waitHandles,
+Int32 millisecondsTimeout, Boolean exitContext, Boolean WaitAll)
+   at System.Threading.WaitHandle.WaitAll(WaitHandle[] waitHandles, Int32
+millisecondsTimeout, Boolean exitContext)
+   at Test.Main()
+How often does this happen? 
+Additional Information:
+When this bug got fixed, it will block our PaintDotNet.exe. (i.e. currently
+our PaintDotNet.exe does not run on .NET)
