summary:
asyncio: sync with Tulip
* Fix a race condition in BaseSubprocessTransport._try_finish().
If the process exited before the _post_init() method was called, scheduling
the call to _call_connection_lost() with call_soon() is wrong:
connection_made() must be called before connection_lost().
Reuse the BaseSubprocessTransport._call() method to schedule the call to
_call_connection_lost() to ensure that connection_made() and
connection_lost() are called in the correct order.
* Add repr(PipeHandle)
* Fix typo
