on Apr 20, 2024 @addaleax ... in test-worker-arraybuffer-zerofill.js... do you happen to remember why the test needed to allocate such huge buffers so often?
function allocBuffers() { Buffer.allocUnsafe(32 * 1024 * 1024); } const interval = setInterval(allocBuffers, 0);
I think this is what is leading to the timeout flakiness in the test.
This file was last changed five years ago so I'll understand if you don't remember ;-)
Btw, I'm assuming it's to ensure that the allocation is expensive enough to ensure that it is likely still running when the other thread allocates?

Additional information
test-worker-arraybuffer-zerofill: this could be a real bug, or some timing assumptions being broken/messages getting lost (which may also be a real bug). We can mark it as flaky for now, and add some logs in the test to help debugging.Originally posted by @joyeecheung in #51362 (comment)
