| /* |
| * Strings are unique by their own contents, since the string itself |
| * is the Key, and the hprof_table.c guarantees that keys don't move, |
| * this works out perfect. Any key in this table can be used as |
| * an char*. |
| * |
| * This does mean that this table has dynamically sized keys. |
| * |
| * Care needs to be taken to make sure the NULL byte is included, not for |
| * the sake of hprof_table.c, but so that the key can be used as a char*. |
