The problem is a fundamental one. Nginx, like many other event loop implementations of servers, presumes that kernel code behaves consistently, precisely and correctly, instead of treating it like a black box, that sometimes lies about things or behaves completely incorrectly, it's not the first time this happened. Any correct event loop implementation should take reported poll events under advisement only and try to schedule reads and writes independently from that.
