DuplexHandle finalizer fix missing...

[Keean Schupke]

(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.
