Hello all,

attached is a draft specifying a minor enhancement to pluginlib which revises the load/create/unload life cycle of libraries.

It enables automatic bookkeeping of created instance and automatically triggers unloading the library when the last instance goes out of scope.
The proposal deprecates one existing method which can lead to difficult usage pattern (ranging from never unloading a library to unloading a library while it is still in use).

The HTML version will be available soon:

Please send comments, questions or feedback.
Due to the small scope I am also asking for your vote (according to the guidelines stated at http://www.ros.org/reps/rep-0010.html).

Best regards,
Dirk
