* Bmalloc provides basic memory allocation without overhead (no free lists). |

|
* Use only to take the load off of malloc for all those |
| 7 |
|
* piddling little requests that you never expect to free. |
| 8 |
|
* Bmalloc defers to malloc for big requests. |
| 9 |
|
* Bfree should hand memory to bmalloc, but it usually fails here. |
