The asan version of this file has the following, which looks like it controls the amount of parallelism in some cases. Since memprof uses shadow memory too (not sure about ctx_profile), we should probably include this here?

```
if not config.parallelism_group:
  config.parallelism_group = 'shadow-memory'
```
