Maybe consider making this `FDGroup::GetFlags()` and have some early returns to
avoid all the else cases? Something like:
```
int GetFlags() const {
if (fdg.read && fdg.write)
return O_NOCTTY | O_CREAT | O_RDWR;
if (fdg.read)
return O_NOCTTY | O_RDONLY;
return O_NOCTTY | O_CREAT | O_WRONLY | O_TRUNC;
}
```
