using distcc with buildworld causes panic

[Daimao]

I was trying out distcc to see if I could get buildworld to work with
it.  Both of my dfly systems are p2 300ish so I thought it would be
really useful to use distcc for building world and the kernel. 
However almost the moment it started, one of the systems got a panic. 
I'm sorry I can't be much more specific about it right now.  I don't
know what I'm supposed to do to get the relevant information to you.
