Hi Sam,

I'll have got again a setup box in the next week and work hard
with bde, gib and tegge to solve them. For RELENG_6_2 it's
too late. I hope to get that small workaround again committed,
but for more serios work we would have to delay 6.2 for half a
year ;-)

The full tty locking stuff is also pendent, maybe I'll grab that
and make it work. Unfortunatly this will open again a new 'can of worms':
new races will appear.
