mdb_txn_commit(txn which made no changes) does not mdb_env_sync(), but lmdb.h says several times that Commit flushes buffers to disk. My feeling is that this is a quirk the user should not need to know about, and it's cleaner to sy r rather than to document it. OTOH I don't know if "fast commit of no-change txns" is a feature which someone expects to work, and if sync can be expensive even when there is no new data to flush. (I don't know what BDB does.)
