Thanks!

This clearly points to SimpleLruWriteAll() added in 77dff5d937b1.
If by chance you will have a backtrace of another deadlocking process -
please post it.

But it's not strictly necessary for analysis, I think we can figure out what
happened from the backtrace you already posted.


Best regards, Andrey Borodin.
