when uploading files UW waits with publishing until all encoding and scaling is done before notifying the user the upload is done, this can take quite some time with large files.
i have tested this with unexperienced users, and they were all sure the uploading died and gave up / refreshed. They didn't think of going to the file page and looking if it was in fact uploaded
I think it would be best to continue to the publishing phase once the original was uploaded if that is technically possible and continue scaling in backround.
