Please don't call abort(3).

My programs usually handle sensitive information. I need destructors
to run to ensure sensitive information is wiped. This is a compliance
item.

I also need to ensure sensitive information does not escape from the
application's security boundary. For example, the sensitive
information should not be written to the file system by way of a core
file; and it should not be egressed to an error reporting service for
the platform provider or application developer to inspect.
