Hi Jens,

Looks like there's a long standing race in the async verification. Does
this patch fix it for you?
So far so good. Been running for about 30 minutes now when previously it
would crash within a minute or two.
Good, that's a lot better... The fix has been committed, btw, that's how
much confidence I have in my fixes ;-)
Let me know how it goes when it has run longer.
Seems to be holding up. I have now run this overnight a couple times without issue.
Great, thanks Steve.
