On Windows, the Platform’s `uv_async_t` may need two iterations before closing when it was previously in use. Refs: nodejs#26089 Refs: nodejs#26006

Should this be in a #ifdef Win32 or similar?

Why not UV_RUN_DEFAULT? My concern is that some platform-specific libuv change may at some point require a different arbitrary number or runs.

@eugeneo Because we want to not keep spinning the event loop indefinitely, which could happen if e.g. addons still have active handles (which we currently crash for, which is what we want).
I agree that this is hacky – hence the TODO – but I wouldn’t expect libuv to change anything here (and if they do, we’d notice because they run Node.js in the libuv CI).
@Fishrock123 I don’t have strong feelings about that, I can add it if you want.

Perhaps we should keep the behavior consistent then.
