I don't quite understand. What happens in this circumstance? 1) My application returns the result of createUploadUrl() to the client (browser). 2) Browser uploads file to that URL. 3) Google tries to call my callback and times out
#3 could be my fault or it could be GAE's; either way, from the perspective of my code, I don't know anything about whether the upload completed. Did this just orphan some stored data in GCS?
