Even with -j3 and smaller swap slices (1.5GBx3) I'd get the odd crash,
always in a different place. Since then, I've modified the build like
this:

1. in /stc/src.conf there's WITHOUT_CLEAN=
2. in /etc/src-env.conf there's WITH_META_MODE= and filemon is loaded.
3. ccache is in use

I'm using -j2 right now because this is building a -current
buildworld where userland is still 15-stable (but kernel is -current)
so maybe there's an extra stress point there.

Also this is the first (ongoing) buildworld with meta mode.
