In short I'm creating a Flash based multiplayer game and I'm now starting to work on the server-side code.  Well I'm the sole developer of the project so I'm seeking a high-level socket library that works well with games to speed up my development time.
I was trying to use the Twisted Framework (for Python) but I'm having some personal issues with it so I'm looking for another solution.
I'm open to either Java or a Python based library.  The main thing is that the library is stable enough for multiplayer games and the library needs to be "high-level" (abstract) since I'm new to socket programming for games.
I want to also note that I will be using the raw binary socket for my Flash game (Actionscript 3.0) since I assume it will be faster than the traditional Flash XML socket.
High-level on one side and raw binary sockets on the other won't work.  Sorry, but you'll need to go low-level on the server side too.
EDIT: in response to the OP's comment.  I am not aware of any "high level" interface of the nature that you are talking about for Java.  And frankly I don't think it makes a lot of sense.  If you are going to talk bytes over Socket streams you really do need to understand the standard JDK Socket / ServerSocket APIs; e.g. timeouts, keep-alive, etc.
