Is the ActiveMQ scheduler lock delay configurable?

Issue

• I have configured a kahadb to use a lock delay by using the following configuration:

<persistenceAdapter>
            <kahaDB directory="/Users/jsherman/Development/tools/jboss-amq/apache-activemq-5.8.0.redhat-60024/data/kahadb">
        <locker>
            <shared-file-locker lockAcquireSleepInterval="5000"/>
        </locker>
        </kahaDB>
</persistenceAdapter>

This allows the slave broker to try to acquire the lock on the kahadb persistence store every 5 seconds.

However, I am still seeing the scheduler trying to acquire the lock every 10 seconds:

2013-12-06 07:29:40,920 | INFO  | Database /Users/jsherman/Development/tools/jboss-amq/apache-activemq-5.8.0.redhat-60024/data/localhost/scheduler/lock is locked... waiting 10 seconds for the database to be unlocked. Reason: java.io.IOException: File '/Users/jsherman/Development/tools/jboss-amq/apache-activemq-5.8.0.redhat-60024/data/localhost/scheduler/lock' could not be locked. | org.apache.activemq.store.kahadb.scheduler.JobSchedulerStoreImpl | main

• Is there anyway to configure the scheduler lock delay?
