I'm confused. That commit 060913999d7a should be backported to
6.1.yy? Since 6.1 lacks this patch, I dont understand your statement
"the race condition doesn't exist there". Or were you trying to say
that the _fix_ for race condition is missing in 6.1?

Or is there some other commit which fixes 060913999d7a that needs to
be backported to 6.1?

Thanks,
