And _perhaps_ this means that 3.10-rc7 without 8aac6270 needs more
time to hit the same bug ;)

Dave, I am not going to "deny the problem". We should investigate it
anyway. And yes, 8aac6270 is not as trivial as it looks.

But so far it is absolutely unclear how it can trigger such a problem,
and none of the traces _look_ as if it should be blamed.

Probably I should try to reproduce too...

Oleg.
