> Extend org.apache.lucene.monitor.MonitorConfiguration with an ability to 
> configure how cache purge task is scheduled by 
> org.apache.lucene.monitor.Monitor (aka Luwak). In particular allow to use an 
> external ScheduledExecutor.
> Currently each new instance of  org.apache.lucene.monitor.Monitor is creating 
> a new thread in order to schedule a periodic cache purge task. This is fine 
> as long as your application is using a small number of Monitor instances but 
> if for some reason you want to create a large number of Monitor instances 
> (e.g. to separate different business domains) you end up with excessive 
> number of threads created.
