         | Yeah, modern JVM is a true miracle and you can be x5 productive
         | (and safe!) compared to C/C++
         | 
         | Do you have any recommendations for a low latency work queue
         | (with in a jvm)?
         | 
         | I want to spawn millions of micro-second-tasks per second, to
         | worker cores..
         | 
         | I am on a massive cache CPU so memory latency hasnt raised its
         | ugly head yet
         | 
         | EDIT: not LMAX please...
