Before you invest too much time in this, I think the rationale for
changing the current behavior so far is very weak. The ideas that have
been floated around in this thread barely cross into nice-to-have
territory, and as a result the acceptable additional complexity to
implement them is very low as well.
Making the OOM behavior less consistent, or introducing very rare
problem behavior (e.g. merely reducing the probability of syscalls
returning -ENOMEM instead of fully eliminating it, re-adding avenues
for deadlocks, no matter how rare, etc.) is a non-starter.
