That's what I said: if you wan tto do this, you need to mark it at _create_ time. Exactly so that the proper exit semantics can be done 100% reliably, instead of just "sometimes". THAT is why _any_ interface that depends on exit_xxxx() must die - because it is inherently broken for accidental deaths, and does not leave the parent any way to recover sanely.
