      Description

      At SAP we have a per thread IO statistic among our supportability enhancements which proved to be very helpful for our support engineers. It might be beneficial for JFR as well.

      The basic idea is simple, we have added fields to the thread class where the number of bytes read and written from/to file and network are counted in. The newly created JFR events are written periodically as for example the ThreadAllocationStatistics event already is.
