Public bug reported:
I've set my CONCURRENCY_LEVEL variable to 8 to use all CPU cores of the
i7. This works fine when compiling programs from the command line. But
whenever dkms needs to compile something, like e.g. the vboxdrv, it only
uses one single core (can be seen with htop) and thus takes a lot
longer.
This is on Ubuntu 13.04 with dkms 2.2.0.3-1.1ubuntu2. I also noticed
this on Quantal with older dkms versions.
