We probably want to test with both `fork()` and `vfork()` here and we want to know if we want to call `exec*()` or not. If we add a `const char *exec_path` to the call and this is not NULL, then we call exec. So maybe change this to be:
```
int call_vfork(int index, bool use_vfork, const char *exec_path)
```
