Message:

Added BSP_MAXIMUM_OPERATION_COUNT and BSP_ITERATION_COUNT
which allow the BSP to override the default number of objects
that will be created in the timing tests. This is useful for
reducing memory consumption on small targets. The BSP_ITERATION_COUNT
can be used to reduce the number of repititions in some of the
tests. This is useful for extremely slow targets (we haven't seen
any slow enough to justify modifying this one yet though. :)

 /*
- *   How many times a particular operation is performed while timed.
+ *  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.
