Not by default, but there's a nice bootable CD with them (and some other 
tools) available from http://www.stresslinux.org/ - and I see they now 
have a version that's bootable from a USB stick, too.

strace isn't touching the hardware, it's just capturing all the system 
calls and signals and logging them before passing them out. That said, you 
can get some really funky results with strace as it can expose all sorts 
of races, since it effectively inserts a delay where one isn't expected.

Enjoy your newfound free time, and feel self-righteous for being 
environmentally friendly at the same time.


Cheers... Dop.
