When I post a multipart-form request I see two files being written
in my temp directory:

  -rw-------  1 ryan users 8318656 2008-09-24 10:51 apreqK5Oiyc
  -rw-------  1 ryan users 8318484 2008-09-24 10:51 apreqQ1qs6C

And:

  Apache2::Request-> new($r)->upload('file')->tempname()

indicates the spool file is "apreqQ1qs6C".

So I wonder what the file "apreqK5Oiyc" is all about.  I imagine it is
used to verify the bytes written and is just standard operating
procedure, but I want to ensure I have not created this situation.

Thanks and Cheers,
