Well, I a gremlin must have triggered a super long gc in between the oncomplete and the onprocessaudio.
I'll let those run in a loop locally to see if I can repro, and check if this is solely due to the oncomplete handler being called too late because of gc or some other stuff, or if we have a bug.

Note - Assuming that the failure seen in https://bugzilla.mozilla.org/show_bug.cgi?id=896582#c24 is alignment with this bug, this test failure in this bug resulted in this web audio test being turned off on Firefox OS emulators.
I can repro very very rarely locally on a Macbook pro, maybe we should just increase the fuzz on MacOS. The test would still be valid, because "actual" would have been 0 before the fix.

Why increase the fuzz factor only on mac?
Because other platform work just fine? The fuzzing is scheduler and load related, and it seems to work fine on other platforms.
Ok, it just seems so fragile to me.
