   Instead moved it to the actual method. Copy-pasting it to multiple places seems redundant.

   JVM thread creation is expensive. It involves initializing the stack memory, creating a corresponding native thread etc.. We may not want to do it for all thread pools for performance sake. We can add other thread pools over time as we see fit but turning it on by default might have some unintended and hard to track down performance issues.
