Hmm. That would have semantics rather substantially different from
the way that the WL_POSTMASTER_DEATH code behaves. But I don't know
how much we care about that, since the whole scenario is something
that should not happen under normal circumstances. Maybe cross-platform
variation is OK as long as it doesn't make the code too hairy.
