+<!-- 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:
