It won't run, it will complain there is another process already running.
What I would do is set autoflush=yes in amanda.conf, then instead of running
a separate cron job just write a wrapper around your amdump job. If the data
is less than your required level, call it with your -o options, if it is
above, call as usual and it will flush everything (including that run) to
tape.
