Thanks Mathias, yes the data storage structure I'm looking to use will
mostly obtained with either by mmap'ing an anonymous segment or
through posix_malign(...) -- not sure of the Windows equivalent. The
storage blocks would basically be chunks in memory, and I'm looking to
make a chain a Boost.Asio compatible ConstBufferSequence.
