In that case, how can I disable the write lock ?
Would commenting LOCK_MUTEX_W() & UNLOCK_MUTEX_W() make the trick ?

You could use MDB_NOTLS in LMDB 0.9.7 or later, but then you must
synchronize threads yourself which does not sound like what you
want. Also, then you must not write when there are too old readers.

Oops, I meant MDB_NOLOCK.  MDB_NOTLS is about readers.
