48 Header file for secure malloc and free routines used by the Counterpane
49 PRNG. Use this code to set up a memory-mapped file out of the system
50 paging file, allocate and free memory from it, and then return
51 the memory to the system registry after having securely overwritten it.
52 Details of the secure overwrite can be found in Gutmann 1996 (Usenix).
53 Trying to explain it here will cause my head to begin to hurt.
