             This module allows you to use in-memory data structures which are

     

       23
       23
       +
             larger than available memory and so are kept in swap.  If you try this

     

       24
       24
       +
             in normal OCaml code, you'll find that the machine quickly descends

     

       25
       25
       +
             into thrashing as the garbage collector repeatedly iterates over

     

       26
       26
       +
             swapped memory structures.  This module lets you break that

     

       27
       27
       +
             limitation.  Of course the module doesn't work by magic :-) If your

     

       28
       28
       +
             program tries to access these large structures, they still need to be

     

       29
       29
       +
             swapped back in, but it is suitable for large, sparsely accessed

     

       30
       30
       +
             structures.

       32
       32
       +
             Secondly, this module allows you to share those structures between

     

       33
       33
       +
             processes.  In this mode, the structures are backed by a disk file,

     

       34
       34
       +
             and any process that has read/write access that disk file can map that

     

       35
       35
       +
             file in and see the structures.
