I agree too.

But seeing how bad the STL performance is when using the default (i.e. 
checked iterator on). I think the least that could be done is to talk 
about it in the documentation and explain how to disable the checked 
iterators (http://boost.org/tools/build/v1/vc-8_0-tools.html seems like 
a good place for this).

A better solution for the user would be to provide an additional 
variable in the VC-8_0 toolset (e.g. bjam "-sVC80_CHECKED_ITERATOR=0"). 
But I dunno whether that's easily feasible.
