Issues with command line

As has been discussed before, when submitting a topology there are really two processes that are started up, with one being the logwriter process and the other being the worker process. When submitting our topology, we independently set TOPOLOGY_WORKER_CHILDOPTS to "-Xmx64m" and TOPOLOGY_WORKER_LOGWRITER_CHILDOPTS to "Xmx2g". When running ps -ef, the logwriter process command displays "-Xmx64m" followed by "-Xmx2g". Why is this? TOPOLOGY_WORKER_CHILDOPTS should be specific to the worker process and should not have any effect on the logwriter process. Is this assumption correct? If so, why does it appear that TOPOLOGY_WORKER_CHILDOPTS appears to be taking precedence over TOPOLOGY_WORKER_LOGWRITER_CHILDOPTS for the logwriter process?
