Tom, thank you for the test package.  It is very well put together,
and I was able to start using it out of the box.

I tried things on my box.  Without compiler optimization enabled (-O3)
and no profiling I get the following timings: (running each executable
with -i):

ttb: (boost)
28.93 user .38 system
tts (Tom Browder's)
24.25 user 0.92 system
ttv (Victor Wagner's)
24.66 user 1.05 system 

With compiler optimization I get much better results:
razeh_at_squirmy:~/timing/tokenizer_test$ make time
ttb: (boost)
16.49 user 0.33 system
tts: (Tom Browder's)
21.46 user 0.95 system
ttv: (Victor Wagner's)
21.91 user 1.00 system

I only ran it twice; the second time the durations didn't change by
more then half a second.

My machine specifications:

I have a 650 MHz Duron running Debian, with the following
