Hi Bjorn,

I've tried to understand how boost::interprocess::string may work in 
conjunction with a mmapped file, but I'm lost in the documentation.

All I've found regards shared memory between processes, but as far as I 
understand, I don't really need shared memory, since all my processing 
will be (for now) on a single process; in the future, threads, so even 
then I won't need shmem.

Is there a document where I can read how to construct a container (or 
better a boost::interprocess::string) without shared memory? I'm not 
hopeful that a doc with boost::interprocess::string and mapped_region 
exists :)

Thanks!
