That's something that Rust fully supports with panic handlers. Doing arbitrary work before the process goes down is useful and supported. (But you will have to be running Linux in a non-default configuration for it to be reliable, of course!)

Thanks, that's good to know!

Of course. It does seem to work in practice with our C++ code, although probably that's due to our usage pattern.
I am one of those few people. We are running some scientific code (currently, unfortunately, written in C++) on a heterogeneous bunch of compute nodes. Some computations can be extremely memory-intensive, and sometimes in ways that we didn't predict. So it's useful to be able to fail gracefully and record that computation X on node Y with input parameters [Z] failed specifically due to running out of memory at step W - so that e.g. the queue manager can try relaunching the computation on a beefier node or adjusting how many instances of which computation are allowed on Y.
