I tried the benchmark on my machine and got much different results.  The
differences between shared_ptr and ptr were much less and
   #define BOOST_DISABLE_THREADS
seemed to slow things up! (based on compare of benchmark1.1.txt and 
benchmark.txt).
My machine takes much longer on the sorts.

Anyway, I'll have to investigate to really figure why, but maybe 
Phillippe's machine
is a lot different than mine:

[evansl_at_localhost evansl]$ uname -a
Linux localhost.localdomain 2.4.18-6mdk #1 Fri Mar 15 02:59:08 CET 2002 
i686 unknown
[evansl_at_localhost evansl]$ g++ -v

The files are in the boost files in directory ptr_evans.
