I agree, but we disagree on requiring 64 bit operating systems or wasting
hundreds of MB of virtual memory for libeio just because your boxes are so
nicely equipped.

I have not yet been convinced of the usefulness or application of such a
feature. You can check the list archives for previous discussions of this
topic.

The only purpose it would serve for you would be, again, to abuse libeio for
not doing I/O but use it for other purposes.

The cost seems quite high for a feature that isn't useful in proper
designs.

Sure, but since that already is broken by design why should libeio acquire
more bloat just for that case? "It could be done" is not a valid argument
in favour of anything.
