Maybe we can have a special allocation function for when the memory
might never be freed.

void* allocate_potentially_unfreed_memory(std::size_t size) {
#ifdef BOOST_SIMPLISTIC_LEAK_CHECKER
    char* result = static_cast<char*>(::operator new(size + 
(std::max)(MAXIMUM_ALIGNMENT, 16)));
    std::strcpy(result, "boost::unfreed");
    return(result + (std::max)(MAXIMUM_ALIGNMENT, 16));
#else
    return(::operator new(size));
#endif
}
