Hi,

For decades there has always been a warning not to do parallel builds of
the kernel or the world (Linux kernel builds also suggest not to do this).

Every once in a while, I see people post about 5 minutes. This only way I
can see this happening is by doing a parallel build (-j 16 on a Xeon
Monster box).

Are parallel builds safe? If not, what are actual risk factors and can they
be mitigated?
