underlying operating system for caching and locking, keeping the code small and
simple.
The use of ‘zero-copy’ memory-mapped files combines the persistence of classic
disk-based databases with high read performance that scales linearly over
multiple cores.  The size of each database is limited only by the size of the
virtual address space — not physical RAM.")
