Log: Don't create a dedicated session for each AIO kernel process. This code dates back to the initial AIO support and the commit log does not explain why it is needed. However, I cannot find anything in the AIO code or the various file methods (fo_read/fo_write) that would change behavior due to using a private session instead of proc0's session.
