You're a few years late, as pretty much nobody agreed with me that the
operating system handling of it was plenty.
I think you misunderstand, we have etc.linux.memoryerror that can
actually throw an error on a null pointer using the signal handler.
I have a suggestion: eliminate this feature, and add a -npe switch to
the compiler that errors on any null pointer usage. Asserts will be
sprinkled in everywhere, but may be useful to someone debugging a nasty
null pointer segfault somewhere.
