Yup, I'm aware of these warnings: they're tracked by a bugs.swift.org ticket.

…apple#46) ### Motivation When running the cancellation tests in a loop, very occasionally there would be a crash with the following backtrace: ``` #0 0x000000018aa008d4 in objc_opt_respondsToSelector () apple#1 0x000000018aea3410 in _outputStreamCallbackFunc () apple#2 0x000000018aea3310 in _signalEventSync () apple#3 0x000000018aeecdb0 in ___signalEventQueue_block_invoke () apple#4 0x000000018abe6cb8 in _dispatch_call_block_and_release () apple#5 0x000000018abe8910 in _dispatch_client_callout () apple#6 0x000000018abefea4 in _dispatch_lane_serial_drain () apple#7 0x000000018abf0a08 in _dispatch_lane_invoke () apple#8 0x000000018abfb61c in _dispatch_root_queue_drain_deferred_wlh () apple#9 0x000000018abfae90 in _dispatch_workloop_worker_thread () apple#10 0x000000018ad96114 in _pthread_wqthread () ``` This seems to indicate that the output stream is trying to access its delegate. However, when running with debug logging enabled I can see that the delegate has already been deinitialized. This is likely a result of the delegate itself owning the stream and setting the stream delegate to `self`, which IIUC is an established pattern. This presents a race in teardown. ### Modifications This patch sets the output stream delegate to `nil` in the delegate `deinit`. ### Result No attempts to call the delegate will happen after it is has been deinitailzed. ### Test Plan With this patch, the failing test passes when run an order of magnitude more times than were required to reliably reproduce the crash without the patch.
