Cleanup tmp dir

[p3drosola]

I'm importing a large amount of attachments in a background job. I can see the attachments are stored in os.tmpDir() + tempfile-*, but they are never cleaned up after the queue has processed them. I'm having to manually clear the tmp directory or else it overruns the entire hard drive.

Thanks, I’ve noted the request and will look into it.
