More user-friendly errors and automatic restarts in case of engines crashing due to OOM

The errors we report in case of OOM and Segmentation-Fault are now much better, but I was wondering is there a way to make them more "user-friendly"?

1. Currently, at least for the MPI case, we report the mpiexec output, which is great, but could there be a way to report a cleaner error in addition to this, that could clearly identify this as a OOM error (or a seg-fault if possible)?
2. Is there something that packages (like Bodo) could do to make this experience better/easier?
3. What's the best way to automate restart of engines in this case? Ideally, if enabled, in cases where the engines crash, if we could clean up the processes, display a message (e.g. "engines crashed due to OOM, restarting engines..."), and then restart the engines, that would be useful.
