It seems problematic if we put the the outstanding thread of asof join into any of the executor, but at this point it's hard to guess the intention of the original author. But the general idea is as @pitrou said, there shouldn't be any kind of waiting (on things that are not guaranteed to happen) in an executor task. As this kind of waiting can easily cause deadlock within a limited number of threads.
