commit67b0025d19upstream. At the moment we can't sanely handle queuing an async request from a multishot context, so disable them. It shouldn't matter as pollable files / socekts don't normally do async. Patching it in __io_read() is not the cleanest way, but it's simpler than other options, so let's fix it there and clean up on top.
