Does this mean everywhere it was requesting the lock/unlock it was really just a no-op and returning error (since mut == null)? |

Yes, but only for the "TimeCB" object table -- which typically is only used once at startup (when still single threaded) and maybe once in SCH. So low impact as far as usage goes. Surprised that this was not noticed before.... |
