When an
StopIteration
raises intoasyncio.Future
, this will causea thread to hang. This commit address this by not raising an exception
and silently transforming the
StopIteration
with aRuntimeError
,which the caller can reconstruct from
fut.exception().__cause__
(cherry picked from commit 4826d52)
