So I mmap(MAP_CONTIG) 1GB working of working memory, prefer some data
structures there, maybe recieve from network, then decide to write
some and not write some other.

Why would you want this?

Because we are receiving a 1GB block of data and then wan to write it to
disk. Maybe we want to modify things a bit and may not write all that we
received.
