26synopsis: "Use data structures larger than available memory"
27description: """
28This module allows you to use in-memory data structures which are
29larger than available memory and so are kept in swap. If you try this
30in normal OCaml code, you'll find that the machine quickly descends
31into thrashing as the garbage collector repeatedly iterates over
32swapped memory structures. This module lets you break that
33limitation. Of course the module doesn't work by magic :-) If your
34program tries to access these large structures, they still need to be
35swapped back in, but it is suitable for large, sparsely accessed
36structures.
37
38Secondly, this module allows you to share those structures between
39processes. In this mode, the structures are backed by a disk file,
40and any process that has read/write access that disk file can map that
41file in and see the structures.
