Tinderbox locks a build when a tinderbuild is running -- you can check
for the existence of a lockfile in the builds/${build_name} directory.

This is why we have a queue for tinderd to deal with.

Have you installed the webui? Have you read the README (try the online
HTML version)? These are both extremely useful for setting up your
environment -- I hardly ever call tc in my general usage.
