I do not believe any version of MSVC supports containers over shared 
memory.  The only compiler I'm aware of that might work is GCC with 
libstdc++-v3.

The Interprocess containers should be clean replacements.  The easy way 
to do the replacement is to just search the boost::interprocess:: 
namespace rather than the std:: namespace, such as with a namespace 
directive:

using namespace boost::interprocess;

Or if you've explicitly qualified your containers as, for example, 
std::vector<T>, just change the std:: to boost::interprocess::.  You'll 
need to change the definition anyway because you need to change the 
allocator type.

And the bad news is that changing the allocator type will make the 
container types incompatible with containers that use the standard 
allocator anyway.  Eg, you can't do: normal_string = shared_string, even 
if they're both templates of std::basic_string, if the template 
parameters are different.
