EpollEventLoopGroup slow shutdown regression
See original GitHub issueExpected behavior
EpollEventLoopGroup regular shutdown takes a few millis to complete.
Actual behavior
EpollEventLoopGroup takes about 1 second to shutdown. This only apply since 4.1.42.Final, it might be related to https://github.com/netty/netty/commit/76592db0bde9d4908191c2d7e54af3466ffd4673#diff-824cfcec3522343772416dd064658a83
Steps to reproduce
Shutdown an EpollEventLoopGroup and wait for its completion. We noticed it because Vert.x testsuite using Epoll on Linux takes much longer than usual (making timeout CI jobs).
Minimal yet complete reproducer code (or URL to code)
Clone https://github.com/eclipse-vertx/vert.x and run mvn test -PtestNativeTransport
