From a process' perspective (or a programmer's perspective); there's a huge difference between random unexpected failure and (e.g.) "mmap()" returning an error that lets you free some virtual memory you were using elsewhere (e.g. for internally caching stuff) and retry (and maybe succeed), or lets you support "partial failure" (where one piece of work is aborted but all other work continues), or at least inform the user/log the problem so the user doesn't assume your software is a buggy piece of crap.

Of course for some languages (e.g. Java) the language itself prevents you from writing code that is able to adequately handle "out of memory" conditions (but even in that case the virtual machine might respond by doing garbage collection).
