The ACCEPT statslog call occurs after connection_init(). Once connection_init
unlocks the connection mutex, any other thread can run, and it looks like in
your case the actual operation threads got started first. We can simply move
the statslog call a bit earlier. Go ahead and move it if you think this is
really a problem, to me it's just cosmetic.
I don't see how this can be responsible for memory access errors. That must be
something unrelated. What valgrind output do you have for that? Most likely
that's your ITS#5050.
