i've used abort() tonight in one of my programs and it just gave a file
named "core".

can't be this.  i've had MANY core files written in my life.  ;-)  core
files are just overwritten, not renamed (permission granting).

i've noticed that whenever opera dumps core, the corefile always has the
number in its name.  that's kind of why i figured it might be a libc
thing that you can control.
