Are you sure that you are running it from a normal user account?

toolhelp is designed to grab variable stuff from all other the memory
which can be done under W95.  NT is kinda real OS and protects access
to resources for unauthorized users; using toolhelp here does not get
you the same kind of stuff as under W95 - if it would, you have story
for Bugtraq.

That's right but it adds code complexity and a performance penalty
with a questionable result.
