Normally, `really_cleanup_for_exit ()' calls `scm_flush_all_ports ()' upon exit. A quick test through GDB shows that `scm_i_terminating', whose sole purpose is to indicate fport code that exception handling cannot be used, is always zero. Did you encounter situations where it was needed? Thanks, Ludo'.
