bq. when it will resolve
Good point.
Shall I change the patch to call JVMStabilityInspector? OOMs are not handled
there at the moment (see CASSANDRA-11818).
EDIT: This would become superfluous when we can stream responses and do not
allocate buffers for the whole response and just for individual frames (or
however the impl would do it).

> With CASSANDRA-12032, Netty throws a
> {{io.netty.util.internal.OutOfDirectMemoryError}} if there's not enough
> off-heap memory for the response buffer. We can easily handle this situation
> and return an error. This is not a condition that destabilizes the system and
> should therefore not passed to {{JVMStabilityInspector}}.
