Re: make -jN (n>1) ineffective in 4.2.0-rc on AMD Phenom

GNU Make 4.1 has a problem that causes it to be unable to use the
desired level of parallelism.  Two people have reported that reverting a
commit which changes from fork to vfork "fixes" it. (i'm one of them,
unfortunately posting as anonymous in the tracker).

Hoewver, if you are also seeing the linux kernel version as relevant to
producing the problem, that's quite interesting, and the underlying
cause may be different.  We reproduced the problem on a range of older
kernels, from 3.2 to 3.18.
