Details:
On modern Systems there is an increasing number of CPU cores/threads. For
example my phone has a gentoo chroot, 8cores and 3GB RAM (shared with the
Android). Compiling c with make -j works fine, python usually too, c++ makes
the system crash. Some packages are written in more than one language.
Additionally the -j switch is set globally in /etc/portage/make.conf and
cannot be switched during an update or rebuild of multiple packages which is a
crucial thing in using a Gentoo system.
I wish to have more options deciding the number of compile threads based on
the amount of ram used or which programming language gets compiled.
