It seems that exiftool when interrupted with SIGINT signal (Ctrl-C) is leaving temporary files around, e.g. DSC_2498.JPG_exiftool_tmp in my case when I interrupted processing of DSC_2498.JPG. Is this something that should be handled more gracefully ?
ExifTool should not leave temporary files around. On SIGINT, it erases temporary files before exiting. I know this mechanism works on Mac/Linux, but I don't recall testing this on Windows. If it doesn't work for you, give me the exact command you are using, and tell me what ExifTool version and system you are running.
