| 58 | paging file, allocate and free memory from it, and then return | |
| 59 | the memory to the system registry after having securely overwritten it. | |
| 60 | Details of the secure overwrite can be found in Gutmann 1996 (Usenix). | |
| 61 | Trying to explain it here will cause my head to begin to hurt. | |
