This is with LuaSocket 3.0.0.

There seem to be more issues, I will revert Copas to the RC, see lunarmodules/copas#114

Copas CI just hangs, see this run: https://github.com/lunarmodules/copas/actions/runs/2167022261

This appears to be a Lua 5.1/LuaJIT specific problem, I can replicate this on LuaJIT but it works fire on vanilla Lua >= 5.2.

I take back my last comment. My testing environment for 5.1 had other issues. I rebuilt luasocket using the correct Lua 5.1 headers and now it works for me both on vanilla Lua 5.1 and LuaJIT.

I've poked at this a bit more and can't come up with any sort of verification that there is an issue at all. Can you review your test case MWE? I'm not saying there is no problem, but I can't help track it down much if I can't get my hands on something that's failing.
