(appologies if this is a repeat) Hi, I have also noticed the fix for DuplexHandle finalizers is not in this release, I believe the finalizer should be attached to the write side (which is pointed to by the read side) but its still attached to the read side as in previous versions... Once again this is a critical fix, as otherwise applications keep one half of the connection open until they quit, or crash due to lack of resources. Keean.
