When performing an upload via the SG API, we have multiple files that share a common filename but are in completely different paths. If we try to upload both of those simultaneously, the AWS upload URL is the same for both.
In _upload_to_storage(), os.path.basename(path) is passed to the _get_attachment_upload_info call. On the AWS side, that means that no matter the parent directory, any file that shares the base name will get a duplicate upload URL.
This only occurs if the _upload_to_storage() call happens concurrently : I'm guessing that the SG backend uses a timestamp to differentiate calls, because currently we do this about 30 times, but only when multiple get called at the same time do we get a duplicate upload URL.

Recommend changing:
filename = os.path.basename(path)to something like:filename = os.path.abspath(path)
