No, an open FD *will* eventually be closed, by the OS when the process
terminates if need be. Unless the machine *crashes* in mid-operation, of
course ...

We do a lot of such transfers, and the (our) gold standard, if possible,
is to do an upload-then-rename under client control, with the further
processing stages on the server requiring a "non-temp name" match.

(Since you didn't specify how exactly you transfer the data: This can be
done with sftp and ssh(*), but not scp.)

(*) E.g., a la "uuencode tempfile < sourcefile | ssh user at host "uudecode
&& mv tempfile finalfile", not that I'd *recommend* such an approach ...
