0041  *  This constant determines the maximum number of a resource
0042  *  that will be created.  For example, some test create multiple
0043  *  blocking tasks to determine the execution time of blocking
0044  *  services.  By default, the blocking time of 100 tasks will
0045  *  be measured.  Small targets often do not have enough memory
0046  *  to create 100 tasks.  By overriding the default OPERATION_COUNT
0047  *  with a lower number (typically 10 or less), all of the time tests
0048  *  can usually be run.  This is stil not very fine-grained but
0049  *  is enough to significantly reduce memory consumption.
