Oops, you are right. I was looking at f6b60983, the one that the
two-patch series should be merged to; there, we remove ASYNC_AS_THREAD
and replace it by NO_PTHREADS. Therefore, I assumed that we use the
former symbol to decide whether to use threaded async procedures.
Obviously, the symbol was introduced only later. Will resend.
