The patch makes the process exit cleanly but complains that there is no
space left. It should be a few GB but it is only a few MB!? I delete 5GB
and controls that the space is usable. Try again but this time it almost
hangs the system, I can blink the leds and move the mouse but noting
more. 
I boot 2.6.36.1 and use a snapshot as root, "emerge libgcrypt" compiles
and installs fine. Boots back into 2.6.37 and try again and the system
hangs again.
