Subject: [PATCH] This condition should NEVER be hit, but in case the started
 thread is unable to locate itself in the EVENT_DISOATCH_QUEUE_THREADS array,
 it's best to return null here and kill the unexpected event thread rather
 than segfault FS by writing outside of the bounds of the
 EVENT_DISPATCH_QUEUE_RUNNING array.
