Whilst you can do this, the risk is that you get other problems if you do that 
(like one DomU running away and Dom0 not getting a chance to run instead :-( 
which is slightly worse, in case you would like to for example KILL that 
DomU!)...  You also want Dom0 to have a high priority (or to be able to run for 
as long as it needs) to be able to correctly and quickly respond to IO requests 
made on behalf of DomU's. Unfortunately, this counteracts the Dom0 being low 
priority...

It's probably a better idea to have a separate DomU that gets to do the 
compiling...
