Interesting. I was thinking that you needed a single line addition:

    sf = c.createSession(username,password)
    sf.detachOnDestroy()  # i.e. don't destroy my session
    cli = omero.cli.CLI()

but that's not working for me either, which I consider a bug. You can
workaround by using a lower-level command, onecmd, but you'll need to
take responsibility for the closing yourself:

try:
    # ....
    cli.onecmd(["import", "a.fake"])
    cli.onecmd(["import", "b.fake"])
finally:
    cli.close()
