Also the traditional plain ftp client on other *ix often doesn't have any
concept of timeut. If a tcp session stalls, it just sits there forever or until
the user issues commands or signals to abort, which means background processes
never timeout. wget/ncftp/curl etc are all more robust choices for automated
operations even if only for that one reason.
