Strange problem with rsync and expect

Yes, you are doing something wrong.  You are using expect to allow a
password to be specified on the command line.  Use ssh key
authentication instead.

Now, as to your problem I couldn't duplicate it.  I started an rsync
of a large file, ^Z suspended it, confirmed that the temp file was
present, then ran another rsync of a different file in the same
directory and the original temp file was not touched or removed by the
subsequent rsync.
