Drain promise resolution

[cedbale]

Hello,

I would like to handle some post action after connection has been drain. After a look into the code, it seems that drain return a promise but i have difficulties to understand when the promise is resolved. By the way it seems that the promise is never resolved.

Is there a possibility to implement an async action like below ?

rdb.getPoolMaster()
        .drain()
        .then(() => {
            console.log('RDB drained');
        })

That should work as far as I know https://github.com/neumino/rethinkdbdash/blob/master/long_test/discovery.js#L407
