03:50 AM Ruby Feature #21642: Introduce `IO::ConnectionResetError` and `IO::BrokenPipeError` as standardized IO-level exceptions.

Thanks for your feedback. I understand your point and I think it makes sense.

Currently, different IO implementations in Ruby raise inconsistent exception types when a connection is reset or broken.
For example:
```ruby
# Plain TCP socket:
socket.read_nonblock(1024)
# => Errno::ECONNRESET
# SSL socket:... ioquatix (Samuel Williams)

The following program can trigger `rb_bug` in `rb_fiber_scheduler_unblock`:
```ruby
require 'async/scheduler'
scheduler = Async::Scheduler.new
Fiber.set_scheduler(scheduler)
Signal.trap(:USR1) do
end
q = Thread::Queue.new
