I don't know the specific timings of the keyboard controllers, but one
generally has to wait for mechanical switches to stop bouncing.  The
contact is not a clean one, but rather a series of brief contacts
as the contacts close, then bounce a part, then close, then bounce...
This continues until the spring finally overcomes the switch bounce.
