We have an update.py running periodically in background, but we also
need to run it manually, for example, run it to update actual_branch,
the manually run usually failed because can't get lockfile, we have to
run it again and again. A timeout option helps a lot in such a case. Now
the following command can make sure we can run the command successfully:
$ update.py -b master -a actual_branch -t 2000
