> LOBs returned from sources cause executions to stay alive until the user query has been completed - this is true even if the LOB values are not returned to the user.
> Whenever an execution is kept alive, it's associated connection is held until the execution is closed - thus source connections may be held out of their pool indefinitely.
> Currently each source execution will attempt to obtain a new connection from the pool, which with LOB handling will cause potentially many connections even to the same source to be held out of the their pool indefinitely.
