* This constant determines the maximum number of a resource
* that will be created. For example, some test create multiple
* blocking tasks to determine the execution time of blocking
* services. By default, the blocking time of 100 tasks will
* be measured. Small targets often do not have enough memory
* to create 100 tasks. By overriding the default OPERATION_COUNT
* with a lower number (typically 10 or less), all of the time tests
* can usually be run. This is stil not very fine-grained but
* is enough to significantly reduce memory consumption.

* times per loop and the body of the loop is repeated "iteration
* count" times. This value is a repitition factor which does
* not increase memory usage -- only execution time.
