Baseline: a2cdeaa

Cherry picks:

• 68c9ba6:
  Fix terrible ForkJoinQuiescingExecutor latent bug exposed by new
  usage of ForkJoinPool: only "adapt" a runnable to run in an
  existing FJP if that existing FJP is the same as the executor's:
  don't enqueue them to run in whatever random FJP is trying to
  enqueue this runnable. Big props to michajlo@ for quickly
  diagnosing this and suggesting the fix.
