The Linux kernel's inability to gracefully handle low memory pressure

I've just checked and it appears that c++'s std::vector::resize may throw std::bad_alloc when malloc fails, but rust's Vec::resize's interface doesn't leave any room to report any errors, so I guess that it will panic...? That's sad.

The standard library assumes infallible allocation, yeah. We have plans to add fallible stuff eventually, but we’re still working on our allocator APIs.

Rust in general will panic on memory allocation failure. There was some discussion about oom handling a while back but I don't know the current state.

Now you regret not putting in exceptions.
