This feature exists, at least.  BuildBot can email people when slaves 
are offline for more than some configured time limit.  I'm not sure if 
the CPython master is configured to do this or not.

It's easy to set up if not, the BuildSlave initializer accepts a list of 
email addresses that will be notified when that slave goes offline, 
notify_on_missing:
