It should not be enabled in the top-level make, in my opinion.
Typically, "make -jN" makes parallel compiles within the same package
(if the package supports it). The parallel build in sage compiles
different packages in parallel, but each package still compiles as -j1.

How hard would it be to let "make -jN" actually work from the top-level make?

This is a request to update the README.txt file used when building from

Since ignoring -jN is non-standard, and since it's important to avoid
surprises when building in parallel, I suggest changing README.txt (at
the top level of the source tree downloaded as sage-6.0.tar.gz) as
follows.

That's it! Everything is automatic and non-interactive. The build
should work fine on all fully supported platforms. If it does not, we
want to know!
