Q:

What is "Pending Activities" in Chrome?

I'm trying to debug a memory leak in my web app.
When recording a heap snapshot, a sizable group is called "Pending Activities", and it seems to hold references to a lot of objects that should not be referenced from anywhere.
Searching online netted nothing.
What is this "Pending Activities" group, and can it be related to my leak?

A:

Turns out that Chrome would not clear DOM memory during JS execution even if it's eligible to be collected; yielding during my execution with requestAnimationFrame allowed Chrome to clear the memory in-between.
