[PD] Behavoir of [keyup] in Linux

[ugur guney]

# Adding a delay worked well. But something is surprising. The [delay] have
to be longer than 0.1 to block this oscillating behavior. I'm attaching a
patch (delaykey.pd) which shows the implementation. I think X11 gives the
"key pressed" message in every 40 msec's or something. So 0.1 delay is not
enough to block these messages.
# and I'm attaching the abstracion I was using in Windows too. (keybin.pd,
keybin-help.pd)

It's just the way X11 works, as far as I understand it.  I did a test
