Okay, when you get this to happen, could you get the output of "core show
locks" from the CLI? Also, please provide a backtrace of all the threads
when this happens. Thanks.

I tried reproducing this myself, and the only way I could make a "logger
reload" or "stop now" command hang was if the queue_log was a FIFO and
there was no process to read from it. If I deleted the FIFO and ran "logger
reload" the queue_log would be recreated as a regular file and everything
worked properly for me.
