+Summary: Synclock Blocks Not Implemented
+Description of Problem:
+Synclock Blocks are not implemented.  In a highly multi-threaded 
+environment the amount code required to get around it becomes cumbersome.
+Steps to reproduce the problem:
+1. Create some code with a Synclock Block.
+2. Try to compile it.
+or 2. Compile it with MS compiler.
+3. Try to run it with Mono
+Actual Results:
+NotImplementedException is thrown.
+Expected Results:
+Synclock should work.
+How often does this happen? 
+Every time.
+Additional Information:
+In order to work around this issue the following code is used:
+Dim o As New Object
+    System.Console.WriteLine("In the lock")
+    System.Threading.Monitor.Exit(o)
+End Try
+The code, with synclock blocks working would look like:
+Dim o As New Object
+Synclock o
+    System.Console.WriteLine("In the lock")
+End Synclock
