Stackstorm action runner does not return / complete - hangs and process is defunct

[camb1997]

When running an action that makes an internal HTTP call (from inside python with requests) that returns a lot of data. The called service is completing and returning HTTP payload over the network (we wiresharked). The action process (we think ?) (after about 15 seconds after the HTTP server returns its data) goes to "defunct" state. The parent process of the action process is the main action runner process. The core.http action works for same call ; we cannot use it because it will publish the output to the workflow and that is too much data to be in the workflow context due to Mongo db driver/performance issues.
