Summary:                    lock (expr) will evaluate expr twice
Description: 
The lock macro evaluates its argument twice.

    <[
      System.Threading.Monitor.Enter ($x);
      try {
        $body
      } finally {
        System.Threading.Monitor.Exit ($x);
      }
    ]>

should probably look like this:

    <[
      def obj = $x : object;
      System.Threading.Monitor.Enter (obj);
      try {
        $body
      } finally {
        System.Threading.Monitor.Exit (obj);
      }
    ]>

Fixed on trunk (r6166).
I also added missing check that locked expression is not value type.
