I'm still having a little trouble.  The allocator they use in
string_test.cpp is one totally implemented there for that project; I'm not
going to have to do / copy that am I?  I've tried:

typedef boost::interprocess::basic_string<char, std::char_traits<char>,
boost::interprocess::allocation_type> BoostString;

AND:

typedef boost::interprocess::allocator<char,
boost::interprocess::managed_shared_memory::segment_manager> CharAllocator;
typedef boost::interprocess::basic_string<char, std::char_traits<char>,
boost::interprocess::CharAllocator> BoostString;

Neither of these bite, I get compiling errors...  "allocator_type" doesn't
work / isn't defined (even with boost::interprocess qualifier).  Am I
missing something?
