But it also states the following:
---
CGI::Simple uses anonymous tempfiles supplied by IO::File to spool
uploaded files to.
---
And DFVCU needs to have a named tempfile.  An anonymous tempfile
usually means that the file is opened for writing and then immediately
deleted while keeping the file open.  This means that you can still
write to the file, but it has no visible directory entry, so no other
user can see or access it.  DFVCU needs to see the file on disk, since
the tools it uses to figure out the file type needs to load the file
to do its tests.

Cheers,

Cees
