 *  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 setting the BSP_MAXIMUM_OPERATION_COUNT
 *  to a lower number (typically 10), all of the time tests can be
 *  run.

 *  count" times.  This value is a repitition factor which does
 *  not increase memory usage -- only execution time.
