Increased memory consumption after update parse to 3.0

Hello, we have an application running on Heroku, that Almost always consumed 256mb to 512mb of memory, but after we updated the version of parse to 3.0 and starts using the async and await functions our memory consume, increase 100%, and now is running in 1GB.
We have a lot of cloud function and before/after saves.
I wonder if it is not the fact that there is no response.success() in the cloud function, and the server never release the resource? How does parse know that running a beforeSave or cloud Function ended for example?

It is probably related to this thread. It should be fixed now. Can you test against the master branch?
