e.g. https://github.com/gfx-rs/wgpu/actions/runs/23169430565/job/67317602988, but pretty sure that's not the first time I've seen this.
[2026-03-16T22:49:54Z INFO wgpu_core::device::global] Device::poll Wait { submission_index: None, timeout: Some(1s) }
thread '<unnamed>' (5372) panicked at tests\tests\wgpu-gpu\poll.rs:99:10:
called `Result::unwrap()` on an `Err` value: Timeout

at D:\a\wgpu\wgpu\tests\tests\wgpu-gpu\poll.rs:99The test has a timeout of 1s, which seems generous for not really doing any work, but not out of the question that we could time out if we get a not-great VM instance.
