I noticed that I'll somewhat unpredictably run into this issue where the kernel prints "IOStream.flush timed out". I found that OutStream.flush() could be called in the I/O thread itself, leading to a wait() that will block for the full 10 second timeout.
I can't reliably reproduce an instance of flush() getting called in the I/O thread, but in my case it looked like a
logger.warningcall inside the asyncio event loop handling was responsible for it.I think this could be the issue in #334 ?
