Hi Paul,

Thanks for the link. It gives me a clue as to what Daniel was thinking.

Yes I am back hacking myth after a long layoff. I am getting too old for 
this stuff! I just spent the last couple of weeks looking for a couple 
of bugs that I would have fixed in 20 minutes a few (well maybe a bit  
more than a few) years ago. I really need to get a new pair of glasses. 
They both proved to be cut and paste bugs one was an extra shriek (!) 
and the other I forget (dementia here I come). I will see if I can track 
down the actual changeset in git from the clues provided. You would 
think after 46 years of hacking code I would have learnt my lesson.

As a complete aside. If anyone reading this is interested in looking at 
another fascinating bug in myth. Try running mythfrontend on a fast 
64bit linux frontend with a ssd drive, and starting the frontend from an 
autostart file. Lots of interesting thread safety issues here! Just 
remember that exit code 139 is probably a SIGSEGV and not a 
GENERIC_EXIT_INVALID_TIME (Darn those overlaps between uncaught signals 
and myth error codes when you are in a shell script ;-) ).
