*default-profiler-limit* is the maximum number of lines of output in profile results. The default value is large to ensure that you receive all possible output requested.
*default-profiler-limit* only counts output lines for functions that are actually called during profiling. Therefore, if
*default-profiler-limit* is 19, and 20 functions were profiled, you would receive full output if one or more of the functions were not actually called during profiling.
