Sort summary of present status: yes, yes, yes! Two days with only one
keyboard hang (down from once every ten minutes). The guess from a
number of people about this being a fight between getty and the
Xserver seems to have been right on the spot. Thanks everyone.

And the one hang exhibited different characteristics than previously
(f.i. the Xserver didn't busy-wait on select()), so for the time being
I regard that as a one-time thingy.

No, I'm happy to say that I haven't seen that...
