#25503 might have solved this?

@gireeshpunathil The last failure appeared in https://ci.nodejs.org/job/node-test-pull-request/20137/ so looks like it's been fixed but I'd suggest we observe for a couple days before closing this.

test: increase timeout in vm-timeout-escape-queuemicrotask
468bfd3 
It looks like under high load the loop isn't even started and therefore
successfully finishes without 'escaping'. After increasing the timeout
during parallel run of the test failure rate decreased from 15/1000 to
0/1000.
