I recently tried to use the std::allocator drop-in replacement from Boost.Pool 
in a massively multithreaded program running on a machine with a lot of cores.
The result was very disappointing. I found my threads being serialized along 
the std::allocator interface (same problem as with the std::allocator from my 
STL).

A nice feature for Boost.Pool would be the ability to scale in multithreaded 
environments (like for example the tbb::scaleable_allocator from the Intel 
Threading Building Blocks).
