- Remove hashbang and tests in runtime package
- Disable test test_close_at_bad_time_for_send_all due to failure on PPC
- Update to v0.17.0
* trio.open_tcp_stream has a new local_address= keyword argument
that can be used on machines with multiple IP addresses to
control which IP is used for the outgoing connection
* If you pass a raw IP address into sendto, it no longer spends
any time trying to resolve the hostname. If you're using UDP,
this should substantially reduce your per-packet overhead
* trio.lowlevel.checkpoint is now much faster
* new, lower-overhead data structure to track upcoming timeouts,
which should make your programs faster
* Trio can now be imported when sys.excepthook is a functools.partial
instance, which might occur in a pytest-qt test function
* The thread cache didn't release its reference to the previous job
* Remove wait_socket_*, notify_socket_closing, notify_fd_closing,
run_sync_in_worker_thread and current_default_worker_thread_limiter
* When using "instruments", you now only "pay for what you use":
if there are no instruments installed that override a particular
hook such as `abc.Instrument.before_task_step`, then Trio doesn't
waste any effort on checking its instruments when the event
corresponding to that hook occurs.
