/*

 *  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.
