There's one thing that prevents using distcc.. Using the -j# option 
causes the build log to get scrambled, because there's no 
synchronization  for that use case in BBv1. So the processing of the log 
for the result generation can't deal with it. If I remember correctly 
Volodya put in handling for this into BBv2.
