Because of things like exhausted semaphores and runaway processes I've taken to
having my build bots reboot after they finish a set of work (using a crontab:
@reboot ./build; sudo /sbin/reboot).  This works great when there is work to do
but when all the work is done the VMs start spinning (rebooting constantly). 
It's not a huge problem but I'd love to have them do something more sane (like
wait quietly until there is work to do).

The best idea I've had so far for solving this would be to have the bot
(optionally) wait (poll on some interval?) until there is work to do.  We would
still want each bot to behave as configured (do one lane of work and then exit
in my case) but this would let my VMs sit completely idle while waiting for

Another idea would be to use exit codes or console output to indicate the
result of the run.  This could be very useful if we decided that a failed build
might need attention (or a retry?) in the future.

I am definitely open to other ideas.
