That is usually application/domain specific though we have talked about 
implementing it before. Any ideas?

The problems is defining "load" - given that it is relatively impossible to 
define generically we would need to define some mechanism for application to 
expose this and fail conditions. And then another monitor application detects 
these status and reacts as appropriate. We already have support for this via 
JMX but no one has really gone deep into that level of control yet.
