I'm trying to plug LMDB into a system where the user first modifies the value,
and only afterwards notifies me that the value has been changed. In LMDB I've
been simply passing the value pointer received from mdb_cursor_get (db opened
with MDB_WRITEMAP), and if the user notifies me that the value has been
changed, I commit the write transaction.
Is this an acceptable use pattern?
No. RTFM.
