  I noticed something similar when I was fixing the console display
output.  The keyboard was acting "strangely":  when depressing multiple
keys, each key release would result in another character event.  Single
keypress/keyrelease worked OK.  Also, key repeating was not functioning.
I did not run it long enough to notice any other problems.

  The replacement of timeout/untimeout to callout was done incorrectly.
The callout structure was added as a union member and overlays the
keyboard state data.  This results in the keyboard code stomping on the
callout data, and the callout processing stomping on the keyboard state
data.

  I have just committed a fix for this problem.
