      It's been mentioned before that core dumps on
some systems may fallow symlink and that this can be used

OS's and versions behave this way.


Well, here's one data point. I just tested under SunOS 4.1.1; a core dump
will follow a symlink, unless the symlink points to a file that the user
can't write, in which case no core will be dumped. I think this is
reasonable behavior.
