I think I'm still leaking and need to properly implement @nobu's advice. |

@ioquatix mentioned an alternative solution would be falling back to blocking I/O with tty devices on kqueue. |

`IO.console.cursor` errors on kqueue-based systems when used with the
fiber scheduler.
```ruby
require 'async'
Async { IO.console(:cursor) }.wait
```
This works on Linux but raises `Errno::EINVAL: Invalid argument` with
`IO_Event_Selector_KQueue_Waiting_register` on macOS.
I don't know if it's an acceptable fix, but this patch just dups file
descriptors for stdin/stdout/stderr if detected alongside kqueue.

I meant to follow up that @ioquatix pointed out this is probably better fixed in the io-event gem by making kqueue synchronous for this use case rather than a hacky solution like mine here. I'd be happy to close this PR and open an Issue if that's preferred. Thanks! |
