That's not the problem, though. The problem is the _ubiquitous_ reliance
on overcommit even where it isn't warranted, and the equally ubiquitous
expectation that an ABEND will do just fine. It won't. An abnormal
termination often will - but a controlled one. A core dump is useless to
anyone except a hardcore hacker. 
If Linux wants to be taken seriously as an alternative to M$ Windows -
as an OS for Auntie Dora and Mr. Thompson the bookkeeper, not just for
you, me, and companies with real sysadmins - its programmers will have
to ditch this habit, and accept that a core dump is _not_ acceptable in
an end-user system. It's bad enough trying to have your computer
illiterate granny report the error message when it _is_ legible; forget
about it when it says "ERRNOMEM - core dumped #*(&$#*(@(@(@".
