Subject: Speeding up virtual keycode scanning

Here is the problem:


GetAsyncKeyState = Win32API.new('user32','GetAsyncKeyState', ['i'], 'i')


while true

  keys.each {|k, v| print k.upcase if GetAsyncKeyState.call(v) & 0x01 ==
1 && GetAsyncKeyState.call(0x10) & 0x01 == 1}
  keys.each {|k, v| print k.downcase if GetAsyncKeyState.call(v) & 0x01
== 1}

end

##keys represents a hash of scan code to virtual keycode conversions.

The problem occurs by running this in a console... pressing "a"
too quickly results in no secondary "a".

In short... it doesn't pick up all the keyboard input unless you type at
1 letter per 3 seconds. Almost like it is cycling through the virtual
keycodes and doesn't get back around to "a" in time.

Any way to speed this up?
