+<!-- Recent Java 6 VMs make calls to JNI Attach/DetachCurrentThread (which this
+     code does extensively) very expensive.  A follow-up JVM fix reduced the
+     overhead significantly again for all threads but the main thread.  So a
+     quick hack to improve performance of this component again is to confine it
+     in the affine apartment (where all code will run on a single, dedicated
+     thread that is guaranteed no to be the main thread).  However, a better fix
+     would still be to redesign the code so that it does not call
+     Attach/DetachCurrentThread so frequently:
