Thanks for the response. I've had a play and here are the conclusions: -

the pl/sql static cursor cache. You can turn the former off by setting
session_cached_cursors to zero, but you can only turn the latter off
has finished. This also happens with
explicit cursors, even if you close them! And it happens whether
session_cached_cursors is set to zero or not. I assume that the cursors are
cached within the session context for the package or procedure since it only
happens for named pl/sql blocks
that with session_cached_cursors = 0, and
a 'commit' following the pl/sql block, the only cursor
appearing in v$open_cursor is the final 'commit'.
