Description
For TCP/stdio/etc the expectation is that poll is routed to zero-length reads/writes on streams, but UDP doesn't have a stream and only has async functions for senc/recv. I don't believe that the same trick of zero-length reads/writes will work here, so currently I don't believe that UDP sockets can get hooked up to poll.

Research direction
Start by reading the WASI poll expectations for TCP and stdio, then compare them with the UDP socket async send/recv APIs named in the issue. Done means agreeing on a concrete way for UDP sockets to participate in poll and identifying the implementation path and tests needed.
