[rules-users] Effect of KnowledgeAgent reload on currently running rules

[Esteban Aliverti]

I'm not sure how the rete is modified and if the modifications are
synchronized with any ongoing operation.
If you want to make sure that the rete is modified when your application is
in a "safe-point", then you will need to turn off ResourceChangeMonitor
service and call its scan() method manually.
We are already doing that in some of Kagent's tests. You can take a look to
these 2 classes:

<https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/agent/BaseKnowledgeAgentTest.java>
https://github.com/droolsjbpm/drools/blob/master/drools-compiler/src/test/java/org/drools/agent/KnowledgeAgentIncrementalChangeSetTest.java
