Thanks! *now* I grok it ;)
That would be a new feature (or bugfix dependent on your POV) for sure.
I was trying to see if there is a way to configure the default deployment timout making it something you can set outside the individual deployment-scanner, but unfortunately seems like its hardcoded to 600 in https://github.com/wildfly/wildfly/blob/master/build/src/main/resources/docs/schema/jboss-as-deployment-scanner_1_1.xsd#L106
@Rob says he is working on an option for this - i'll let him create/point to the jira.
