Mysterious HTMLRewriter Issue – Async Bug or PEBKAC?

UPDATE: this was solved, thanks to the Cloudflare Community Discord. See comments for the solution.

I've been wanting to kick the tires with Cloudflare's HTMLRewriter to see if it could be used as an HTML parser. As a simple example, can Cloudflare Workers + HTMLRewriter be used to build an API to parse OpenGraph metadata and return the properties as a JSON document? Based on a cursory review of the documentation, it appears as if this should be quite simple.

However, I have observed a race condition where HTMLRewriter will always find fewer than the present number of matching elements unless a simulate a 1 millisecond "sleep":

await new Promise( function(resolve) { setTimeout(resolve, 1); })

UPDATE (2017-10-20): it has recently been brought to my attention that this gist has been circulated amongst Sensu users as a sort of best practice or "guide". This gist was never meant to be adopted as a long-term solution, but rather an alternative/temporary solution while many changes regarding Sensu event filtering were "in-flight". Many more words regarding changes to event filtering have been captured on the Sensu blog since the writing of this gist: https://blog.sensuapp.org/deprecating-event-filtering-in-sensu-plugin-b60c7c500be3. The TL;DR here is: use the new built-in occurrence filtering that has been available in Sensu Core since version 0.26.0 (release notes).

Hi friends.

There has been a lot of confusion over the past few months about how the Sensu check definition attributes occurrences and refresh actually work. The attributes occurrences and refresh are not (currently) a part of the Sensu [check definitio
