1. [New comment] PythonSocket -- unhandled exception in Finalize() in restricted AppDomain
http://ironpython.codeplex.com/workitem/33779
User KeithJRome has commented on the issue:

"Most likely has something to do with the fact that the finalization queue is run on the finalizer thread. The finalizer calls _close(), which in turn tries to delist the socket from the static dictionary _handleToSocket. But to get the key used in that dictionary, it uses the Handle property, which makes a CAS demand on SecurityPermissionFlag.UnmanagedCode. And I guess the finalizer thread is not endowed with that permission.

Seems like the least nasty fix might be to change how _close() searches for the socket in that dictionary... doing a brute-force lookup by value instead of by key and removing it that way? This would avoid any attempts to dereference the Handle property of the Socket during finalization."
