std.io.poll broken on Windows

[DivergentClouds]

Zig Version

0.14.0-dev.3287+65e7ede49

Steps to Reproduce and Observed Behavior

Running the following tests on Windows,results in the first 2 tests hanging and the third returning an error. You must use test filters to run all tests.

const std = @import("std");
const builtin = @import("builtin");

test "poll stdin" {
    const allocator = std.testing.allocator;
    var poller = std.io.poll(
        allocator,
        enum { stdin },
        .{ .stdin = std.io.getStdIn() },
    );
    defer poller.deinit();

    // never returns
    _ = try poller.pollTimeout(1);
}

test "poll file with data" {
    const allocator = std.testing.allocator;
    var tmp = std.testing.tmpDir(.{});
    defer tmp.cleanup();

    const file = try tmp.dir.createFile("foo", .{ .read = true });
    defer file.close();

    try file.writeAll("bar");

    var poller = std.io.poll(
        allocator,
        enum { file },
        .{ .file = file },
    );
    defer poller.deinit();
    // never returns
    _ = try poller.pollTimeout(1);
}

test "poll empty file" {
    const allocator = std.testing.allocator;
    var tmp = std.testing.tmpDir(.{});
    defer tmp.cleanup();

    const file = try tmp.dir.createFile("foo", .{ .read = true });
    defer file.close();

    var poller = std.io.poll(
        allocator,
        enum { file },
        .{ .file = file },
    );
    defer poller.deinit();
    // fails with `error.Unexpected: GetLastError(38): Reached the end of the file.`
    _ = try poller.pollTimeout(1);
}

Expected Behavior

All tests should return successfully. This behaves correctly on Linux.
