pywheel version deadlocks GIL on OSError

[stevarino]

Calling InputDevice.read() or InputDevice.read_one() on a file that was deleted (such as removing the USB device) was causing a hang for me (notice the KeyboardInterrupt after the OSError, my code has no threading or exception handling):

Traceback (most recent call last):
  File "/home/stevarino/mpv/x11.py", line 78, in <module>
    main()
  File "/home/stevarino/mpv/x11.py", line 19, in main
    run(dev)
  File "/home/stevarino/mpv/x11.py", line 28, in run
    event: InputEvent = dev.read_one()
                        ^^^^^^^^^^^^^^
  File "/home/stevarino/mpv/env/lib/python3.11/site-packages/evdev/eventio.py", line 58, in read_one
    event = _input.device_read(self.fd)
            ^^^^^^^^^^^^^^^^^^^^^^^^^^^
OSError: [Errno 19] No such device
^CException ignored in: <module 'threading' from '/usr/lib/python3.11/threading.py'>
Traceback (most recent call last):
  File "/usr/lib/python3.11/threading.py", line 1583, in _shutdown
    lock.acquire()
KeyboardInterrupt:

I forked and built the source fairly easy and began debugging why this is happening, inspecting the read call errno, adding fprintf calls, and I noticed that it had stopped hanging immediately after installing my locally built version.
