I'm trying to find a way to make a program run truly quiet, i.e. no STDOUT/STDERR until the main routines finish. After running, I want to analyze the STDOUT/STDERR, filter it, and make choices based on the results.

The catch: I want to avoid creating any files in the process.

I've looked at the example from chapter 16 of The Perl Cookbook, but I don't quite get it.
