You are right. I don't know any STL implementation fully compatible with 
Boost.Interprocess allocators, but I haven't tested recent gcc (4.0 or 
newer) or Msvc 8.0 STL containers. And this is the main reason to offer 
specialized containers. Last time I checked STLport and the Rogue Wave 
STL (stdcxx) weren't compatible.
