that is built. This saves a lot of time, especiall when the
parallelism (the number of jobs per machine, not the number of
machines) is low.
However, the build script only blows away /usr/local and
/usr/X11R6, so if there is a port that does some nasty things
outside that area, all bets are off.
(2) Better load balancing. Now, each machine reports its own
load in a form of a text file, which the master merely aggregates
to pick the lowest-loaded machine(s). Other than generally
running faster (and more up-to-date) under loaded conditions, the
master script will no longer hold up until a timeout when a
machine goes down.
