[Buildbot-devel] way to tell slave to disconnect after current build finishes?

[Stephen Davis]

Sometimes, I need to take a bot offline temporarily to update the dev 
environment or what-have-you -- quite often to fix the build pertinent 
to that slave b/c it is the only machine with that dev environment.  
Right now, I just ctrl-c the slave process and it shuts down cleanly 
but leaves the build in the "interrupted" state on the master which 
shows red in the status box.  Red is bad.

Is there any way to send some signal or command to the slave to have it 
disconnect when its current build is finished?  That way, it'd be in a 
clean state the next time it starts up and the build status would be 
its expected last value instead of "interrupted".  A mechanism to do so 
either on the slave host or via the master would be cool.

Have you noticed that, once you start to get users, they start making 
all kinds of demands?  :-P
