I don't know what the correct thing to do, but you can easily detect processes that have the LD_PRELOAD environment variable defined. This is a rare enough use case for manual inspection. Something like
```
for f in /proc/*/environ ; do sudo strings $f | >/dev/null grep LD_PRELOAD && echo $f; done
```
``` for f in /proc/*/environ ; do sudo strings $f | >/dev/null grep LD_PRELOAD && echo $f; done ```
