Looking at the history of these tests on iOS, it appears that the failures may have been arm64 only, so it became more apparent when we moved bots to M2 hardware. https://results.webkit.org/?suite=api-tests&suite=api-tests&test=TestWebKitAPI.GPUProcess.ExitsUnderMemoryPressureWebAudioCase&test=TestWebKitAPI.GPUProcess.ExitsUnderMemoryPressureWebAudioNonRenderingAudioContext&platform=ios&recent=False&architecture=arm64 This appears to be the regression range: http://commits.webkit.org/compare/260393@main...260364@main
