That works, thank you, tilly.
It's moot now, but I'm still puzzled by the warning in the File::Temp doc:
"For maximum security, endeavour always to avoid ever looking at, touching, or even imputing the existence of the filename. ...
"If you need to pass the handle to something that expects a filename then use ... "+<=&" . fileno($fh) for Perl programs."
Must depend on the internals of sendfile as you say.
