      Description

      It is currently difficult to be sure whether a workload is I/O bound from looking at statistics. If we tracked how many threads were in a read or write system call when statistics are gathered, we could compare that with the number of threads in the library to get an indication of whether they are spending a significant amount of time on I/O.
