Robin Berjon thought I should post this as a heads-up to anyone thinking
what I thought: "XS or pure perl code will always be faster than backticks
or system() calls".
Wrong.
I spent some time converting some of our backtick programs to XS code here,
and the result was absolutely zero difference in performance.
I posted to c.l.p.moderated about this. The thread is here:

The OS was Linux (tested on kernel's 2.2 and 2.4). I think it's probably
fairly OS dependant, but I figure most people are on linux.
