MAKE_JOBS_SAFE uses make -j on a single port (when in the WRKSRC
directory) but does *not* build multiple ports at the same time,

What *would* happen is that make would try to build multiple ports at
once. This is not supported.

This is what I said. This feature is automatic and does not require -j

I've seen that work: it looked quite good. Yes, I think this would be
very useful and I think a lot of people would want it :-).
