Is there a reason to decrease dea pool memory when we send a staging task? Reservation of at least app memory in stager pool gives DEA chance to start the instance on the same DEA the app was staged as stager pool memory will be released before app is started. At the same time 5 seconds (DEA advertisement interval) is not enough time for staging task to finish and start an instance. The next dea advertisement will overwrite the dea pool memory. So it does not make sense to reserve double memory ahead.
