Windows, x86, COMPlus_JitStressRegs=8

https://dev.azure.com/dnceng/public/_build/results?buildId=726304&view=ms.vss-test-web.build-test-results-tab&runId=22490824&resultId=102068&paneView=dotnet-dnceng.dnceng-build-release-tasks.helix-test-information-tab

I don't think this is related to JitStressRegs; I can't repro it locally like that. I think the test simply fails sometimes on loaded systems due to this code:

            // Wait for compaction to complete
            Assert.True(await sem.WaitAsync(TimeSpan.FromSeconds(10)));

Kusto shows 6 such failures in the last 30 days (all Windows x86, JitStress).

Could this timeout number be made much, much higher?
