Sometimes the files are so small, or the net connection is 
so fast, that the file gets uploaded before any info can be 
retrieved from the progress module. In these cases the 
progress info will be null, and there is no way of knowing 
whether the file has been uploaded or it is still starting 
to getting uploaded.

Well, the above is not entirely true, When the file upload 
has ended, the upload script could indicate (with 
Javascript) that upload is done, but there are problems with 
that: output buffering:

"Several servers, especially on Win32, will still buffer the 
output from your script until it terminates before 
transmitting the results to the browser. " etc...

So. In order to get timely response about the status of the 
upload, it would be best to get the info from the progress 
meter: whether the file has been actually uploaded. 

A new flag (in the return data by uploadprogress_get_info) 
or something like that would do the job, I think. That wold 
mean that the temporary file would need to be preserved for 
a while, at least, and not deleted instantly.
