This worked great. Our CPU utilization went to 0 down from 25%.

You're getting so many slices that your CPU is consumed with this one task of checking the type-ahead buffer. It's frenetic, a CPU on crystal meth. In the old days, we would say Release Timeslices RQM. Today you can solve that issue as well, by adding a Sleep for a 1 second. On systems that allow sleeping for periods less than a second, you only really need to add a sleep for a tenth of a second, to see your CPU suddenly quiesce.
