It looks like mdb_drop0() should also reset/uninitialize other cursors in the same (sub)database. Currently such cursors keep any references to the deleted pages.

Just doc this. No cursors should be open on a DB that is being dropped.

Doesn't help mdb_cursor_del's call to mdb_drop0 when F_SUBDATA. Is that safe?

Probably not but again, it's a doc issue. Someone has to call specifically with the flag mdb_cursor_del(MDB_NODUPDATA) so they must know what they're intending.
