   Have you come across Ruby's profile facility?

I find that profiling is a useful but somewhat crude tool for tuning
performance.  Sometimes I need to instrument specific blocks of code;
othertimes I need to report incremental resource utilization in a
long-running program.  Profiling, while useful in many circumstances,
is not a replacement for instrumenting system resources.
