Full ACK.

That's questionable, depending on the real bottlenecks in compiler 
operation. I suspect that disk I/O is the narrowest bottleneck, that can 
not be widened by parallel processing. It also requires further 
research, for e.g. the determination of the optimal number of threads, 
depending on the currently available resources on a concrete machine.

But of course it's worth a try, to find out more...
