| 35 | They're named weirdly so that the intercept code can find them when the |
| 36 | shared object is initially loaded. |

| 38 | Note that this filename has the "drd_" prefix because it can appear |
| 39 | in stack traces, and the "drd_" makes it a little clearer that it |
| 40 | originates from Valgrind. |
