Request for API OWNERs' feedback for microwaiting in JS

[Shu-yu Guo]

Hello blink API OWNERs,

I'm requesting early feedback on https://github.com/syg/proposal-atomics-microwait. Specifically, the clampTimeoutIfCannotBlock option, as it proposes relaxing the "main thread cannot block" restriction.

NB This is not yet (but will be) presented at TC39 in February.

Thanks,

shu
