Actually the berkeley make has parallelising capabilities, and the NetBSD build
system can use it.
The problem is that it will start all commands on the same host.
We could either modify make to have it rsh the command to another host,
or change the various commands to execute on a pool of machine is a
round-robind fasion (sh wrapper would be enouth).
I think the first solution is the best, can if done rigth could even be
integrated back in the NetBSD make.
The only problem is that the source tree needs to be shared among all machines
(from a NFS server), so doing this over the whole internet is not a solution.
