This is a tricky one, but there is definitely something wrong going on here, both with and without ANGLE.

This test is skipped in most configurations, and marked as a flaky timeout in the few configurations where it runs. But it also appears to be skipped on internal bots (although I don't understand how), so we don't have results from different hardware configurations.

LayoutTests/TestExpectations:3823:webgl/1.0.3/conformance/glsl/misc/shader-with-reserved-words.html [ Skip ]
LayoutTests/platform/mac-wk1/TestExpectations:583:webkit.org/b/170877 [ Debug ] webgl/1.0.3/conformance/glsl/misc/shader-with-reserved-words.html [ Pass Timeout ]
LayoutTests/platform/mac/TestExpectations:1728:webkit.org/b/170877 [ Debug ] webgl/1.0.3/conformance/glsl/misc/shader-with-reserved-words.html [ Pass Timeout ]

Anyway, this test times out on Mac minis with or without ANGLE. It passes on iMac16,2, also with or without. It presumably timed out in a different way on Dean's iMac Pro (?), making him land this "#PID UNRESPONSIVE" expectation.

Reusing this but to track all issues with this test.

I've identified a regression in shader compilation performance with ANGLE enabled, so I will fix that. After fixing the regression the performance should be the same with and without ANGLE, so if it was timing out before then it will probably still timeout.
