+- ftp: prevent server from hanging on closed data connection
+
+ Some FTP servers (e.g. Pure-ftpd) end up hanging if we close the data
+ connection before transferring all the requested data. If we send ABOR
+ in that case, it prevents the server from hanging.

+ Bug: https://bugzilla.redhat.com/643656
