Thanks.  Actually, though, what I'm talking about is a different archive
type, not a data structure.  Right now binary data is saved/restored using
read/write.  mmap is potentially much more efficient for large data
structures. OTOH, there is one big problem for it, which is that mmap can
only be applied to one contiguous memory region.  I believe you would have
to serialize one object to one file, and if you want more objects you would
need multiple files to map them to.  Still, might be interesting.
