I don't seem to be very good at programming bugs :( I could not
reproduce the same circumstance that crashes the xen server. This means
that it is possible more corner cases that have to come together before
xen crashes. 
But when there is a version that crashes the xen server it will do so
systematically. I'm going to continue developing AROS and when I have an
executable again that crashes the xen server I'll post it here.

Staf.
