- * Module for CPU profiling based on periodic pc-sampling.
- *
- * For full(er) information, see doc/cpuprofile.html
- *
- * This module is linked into your program with
- * no slowdown caused by this unless you activate the profiler
- * using one of the following methods:
- *
- *    1. Before starting the program, set the environment variable
- *       "CPUPROFILE" to be the name of the file to which the profile
- *       data should be written.
- *
- *    2. Programmatically, start and stop the profiler using the
- *       routines "ProfilerStart(filename)" and "ProfilerStop()".
- *
- *
- * (Note: if using linux 2.4 or earlier, only the main thread may be
- * profiled.)
- *
- * Use pprof to view the resulting profile output.
- *    % pprof <path_to_executable> <profile_file_name>
- *    % pprof --gv  <path_to_executable> <profile_file_name>
- *
- * These functions are thread-safe.
