While I share my opinion here, I don't mean that to block Madhavan's
work.  I'd rather defer to people more knowledgeable in current userland
and ABI issues/limitations and plans on dealing with those, especially
to Florian Weimer.  I haven't seen Florian say anything specific for or
against Madhavan's proposal, and I'd like to.  (Have I missed that?)

I think it's unnecessary for the libffi use case.

I don't know if kernel support could
make sense in this context, but it would be a completely different
patch.

Thanks.  Are there currently relevant use cases where the proposed
trampfd would be useful and likely actually made use of by userland -
e.g., specific userland project developers saying they'd use it, or
Madhavan intending to develop and contribute userland patches?
