The manual currently does not list abort as an action which flushes any
I think you are making up an implementation constraint which does not
What I'm trying to do is to get rid of the flushing (to get a cleaner
process termination sequence) while preserving the legacy behavior that
stdout/stderr and other file buffers are flushed on termination because
that's easily user-visible. Considering that flushing streams which are
not file-backed can allocate memory using malloc and that abort can be
called from all kinds of contexts (including malloc itself), I think
that's a reasonable precaution.
