Description
The Verilog server unit tests check for certain timing-based behavior that frequently fails on macOS during a run of the uploadReleaseArtifacts CI job, for example https://github.com/llvm/circt/actions/runs/19579832326/job/56509187173. Re-running the job usually works, but it would be good to have CI be either a robust pass or failure. I'm going to disable this test on macOS until we can get a fix in.
@uenoku @Scheremo, I think you have been poking at this test and improving it in the past. Do you know of any way to fix this? We should probably include a macOS CI run somewhere in nightly CI, to avoid us finding macOS CI failures only after cutting a release when the artifact upload job runs.

Research direction
Start with the Verilog server unit tests and the uploadReleaseArtifacts CI job, using the linked macOS failure as the reproduction point. Investigate the timing-based check on macOS; done means the test produces reliable CI results instead of requiring reruns, with macOS coverage considered for nightly CI.
