get_gamepad seems to block

For my application it is crucial to check if there are new events but if not, proceed with the other code. However: In order to check for new events I need to call get_gamepad which calls internal read on the device. This function seems to block until an event arrives. It would be awesome to add a nonblocking read or an option to specify all reads as nonblocking!

As always: Thanks for your library!

I added this in the _character_device() in the InputDevice class:

self._character_file = io.open(
  self._character_device_path, 'rb')
fd = self._character_file.fileno()
flag = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, flag | os.O_NONBLOCK)

And then calling this in my code:

events = devices.gamepads[0]._do_iter()

To bypass the while True loop in iter(). Not so pretty but hey, it worked for me!

I think adding this flag and also yeilding an empty array in iter() if there is no data would be a nice complete solution but I never tried it.

why was the blocking parameter never added to inputs? I either need to run part of my input handling in a seperate thread or I need to edit inputs to be nonblocking. it reduces my programs fps from 3000 to about 200 with most of the time being spent waiting for inputs.get_gamepad()
