The attached cursor-del-break.c exhibits an assertion failure after successfully
deleting 1246 256-byte records from a set of 2048. This hammers the case where
one cursor is used to iterate, while a temporary cursor is used to delete the
record currently pointed to by the first cursor.

cursor-del-break: src/py-lmdb/lib/mdb.c:5025: mdb_cursor_next: Assertion
`((((mp)->mp_flags) & (0x02)) == (0x02))' failed.
