Why not just move the temporary file and rename it in one operation? On
most filesystems this is a very fast thing. This seems to me to be a
perfect example when a temporary file is good, since it is converted to
a permanent file.

If the alternative is to have a stream into memory, prepare your server
for the case when user decides to upload a zip file containing his
collection of Hollywood movies in HDTV quality :-)

Maybe a choice would be best, but are the temp files really a problem?
